DESCRIPTION:Space-charge-dominated beams are of increasing interest in the
light of proposed high-current projects like spallation sources\, proton
drivers\, radioactive beam facilities and inertial fusion. Coherent space
charge effects associated with space charge raise new issues. Some of them
have been studied experimentally with the SIS and ESR \nmachines at GSI a
nd interpreted by means of computer simulation programs developed for this
purpose. Examples are measurements on longitudinal instabilities as well
as on transverse quadrupolar oscillations used for emittance measurements.
\nWe also present results on coherent tune shift effects during resonance
crossing and apply them to multiturn injection with skew quadrupoles and
to bunch compression. \nPossible applications to future projects at GSI ar
e discussed.Organiser(s): B. AUTIN/PS\n\nhttp://indico.cern.ch/conferenceD

DESCRIPTION:The CRYRING accelerator complex consists of low-energy ion-sou
rces \nand of a storage ring equipped with an electron cooler The ion-sour
ce is of EBIS-type and can deliver highly charged ions all over the period
ic system. A similar source will be used as a charge breeder for REX at IS
OLDE and may be of interest for LHC. The electron beam is used not only as
a cooler but also as a target for studying collisions with atomic and mol
ecular ions. It was recently upgraded with a super-conducting solenoid and
a new electron gun so that it is adiabatically expanded by a factor of 10
0 and its transverse momentum spread is reduced by the same factor. The CR
YRING facility will be described together with an overview of the current
research in atomic and molecular physics. MSL involvement into CERN projec
ts will also be addressed.\n\nOrganiser(s): B. Autin/PS\n\nhttp://indico.c

DESCRIPTION:The Compact LInear Collider (CLIC) studied at CERN aims at ene
rgies as high as 5 TeV in the center of mass and a luminosity of 1035 cm-2
s-1 and is thus an accelerator contemplated for the post-LHC era. The len
gth and cost of the overall complex is minimized by using high acceleratin
g fields (150 MV/m) produced in 30 GHz normal-conducting structures by an
intense low energy primary electron beam. The two beam acceleration techni
que is potentially cost effective to generate the RF power (400 MW/m) requ
ired by such machines. In its present version\, it relies on a novel schem
e which will be tested in a new test facility (CTF3). \nThe results of CTF
2 and the design of CTF3 will be presented.Organiser(s): B. Autin / PS Div

DESCRIPTION:The energy exchange between the degrees of freedom of a multi-
dimensional oscillator is a widespread phenomenon. A new two-dimensional f
ormalism has been derived to extend the one-dimensional results of transve
rse coherent instabilities in the presence of x-y coupling. It shows that
coupling between the transverse planes of \na particle beam leads to a sha
ring of the oscillation energy\, including the growth rates of coherent in
stabilities. Furthermore\, in the presence of a frequency spread\, there c
an also be a partition of Landau damping for 'optimum' coupling. Measureme
nts performed in the CERN-PS for the LHC beam and applications to other ma
chines \nwill be discussed.\n\nOrganiser(s): B. Autin/PS\n\nhttp://indico.

DESCRIPTION:In a dedicated muon ring\, the high flux of electron and muon
neutrino beams produced by muon decay would point towards far or close det
ectors opening up a whole new class of neutrino physics. This is the conce

tance cooling are necessary to make a Neutrino Factory (or a Muon Collider
) a possible future high energy physics facility. The Neutrino Factory and
Muon Collider Collaboration studies the different subsystems and presentl
y focuses on a 20 - 50 GeV muon decay ring. A neutrino factory located on
the Fermilab site and recent developments in ionization cooling will be pr

DESCRIPTION:The E-157 Plasma Wakefield Acceleration (PWFA) experiment aims
at studying the acceleration of electrons submitted to fields exceeding 1
00 MV/m in underdense lithium plasmas. The electrons of the head of the bu
nch completely expel the plasma electrons\, and create a pure ion channel
for the core of the bunch to propagate through. The ion channel radial ele
ctric field exerts a strong focusing force on the bunch core leading to mu
ltiple betatron oscillations of the electron bunch. Behind the bunch core\
, the plasma electrons rush back into the ion channel and generate a large
amplitude longitudinal electric field: the wake field. The plasma density
is tuned so that the bunch trailing electrons experience the maximum wake
field during their acceleration. The experimental set-up\, as well as res
ults regarding betatron oscillations\, bunches tail flipping\, beams refra
ction\, x-ray emission\, and energy gain will be presented.Organiser(s): B

DESCRIPTION:Increasing the energy of radioactive ion beams can considerabl

. The energy would be upgraded to 2.5 MeV/m then to 3-6 MeV/m using a new
design of IH-RFQ structure at 101 MHz and a 7-gap IH resonator at 202 MHz.
Moreover\, the yield of reactions with radioactive beams can be multiplie
d by two to three orders of magnitude by adding a recirculator since all c
harge states leaving the target are recycled with the initial energy (6 Me
V/m) but at the cost of a large momentum spread (+20%).\n\nOrganiser(s): B

DESCRIPTION:Radioactive Nuclear Beams will be the tool of choice for nucle
ar physics and nuclear astrophysics for the beginning of the 21st century.
The challenging task is to make secondary beams of very unstable nuclei w
ith intensities that could approach those of today's stable beams (EURISOL
proposal). Among the most interesting beams are the neutron-rich fission
fragments. Their production is envisaged using fast neutrons interacting w
ith uranium or other fissile targets. This technique relies on a high inte
nsity proton accelerator. An alternative method is based on high-energy ga
mma radiation to induce photofission. IPN Orsay has installed the detector
PARRNe-1 in the 50 MeV electron beam of the LEP-injector. Data of high qu
ality have been obtained and will be presented. The two methods of product
ion will be compared and an outlook of the perspectives will be given.Orga

DESCRIPTION:To continuously optimize the transverse emittance of the proto

matching. For this reason\, a quadrupole pick-up has been developed for th
e CERN PS. This pick-up is sensitive to the transverse beam size\, and det
ects beam width oscillations caused by injection mismatch. Unlike previous
cases\, the instrument is custom-built\, and not merely a position pick-u
p with enhanced electronics. With the two pick-ups that are now installed
in the machine\, it is possible to determine not only the matching\, but a
lso the emittance of each bunch in the injected beam. The talk gives an ov
erview of the pick-up design\, describes the methods used to acquire and a
nalyze the data\, and presents some measurement results\, including compar
isons with other instruments in the machine. Applications in other machine

number of mass market applications\, particularly in the communications\,
image/video processing and control/data acquisition areas. Today\, the ent
ire wireless industry operates with DSP-enabled handsets and base \nstatio
ns. Other examples of DSP-based applications include digital cameras\, med
ical instrumentation and motor control. As a side effect\, constant improv
ement in DSP hardware has also fuelled digital signal processing research\
, contributing to advancements in fields such as multimedia signal process
ing and adaptive filter design.\nCERN has already taken advantage of this
technology for several crucial systems\, in the diagnostics\, control and
data acquisition sectors. Examples are tune and intensity measurements\, p
ower supply digital regulation and detector implementation in experiments.
The seminar gives an overview on DSPs history\, principles and use. This
coverage is then revisited by examining existing operational DSP applicati
ons in the PS division\, such as the AD intensity and tune measurement sys
tem. Some hints are finally given on possible future DSP implementations w

DESCRIPTION:During the years 1996-1999 the 'Proton and Ion Medical Synchro
tron Study' (PIMSS) was held in the PS division under the leadership of Ph
il Bryant. The results of this study have been used by the TERA Foundation
to propose the creation of the National Centre for Hadrontherapy (CNA)\,
that will feature three treatment rooms where patients will be treated wit
h beams of protons and carbon ions. In 2001 the Italian government has cre
ated the CNAO Foundation to realize such a centre in Milano\, and in July
2002 TERA has been given the responsibility to prepare\, by September 2003
\, the specifications and technical drawings of all the components of the
synchroton and of the medical beam lines.\n\nThe four contributions\, last
ing about 25 minutes each\, will concern:\n\n(1) the rationale of hadronth
erapy and the clinical results obtained with protons and carbon ions\,\n\n
(2) the layout of the centre and its construction and future use\,\n\n(3)
the technical choices made in the final design of the synchrotron and of t
he dose delivery systems\,\n\n(4) a description of some crucial components
\, and in particular of the injection chain and the RF system.\nOrganiser(

SUMMARY:CTF3 - a staged test facility - why is it so important for CLIC?\n

DESCRIPTION:The design of CLIC (Compact LInear Collider) is based on a two
-beam acceleration scheme\, where pulses of high power 30 GHz RF are gener
ated by a drive beam running parallel to the main beam. \n\nThe third gene
ration CLIC Test Facility (CTF3) is to demonstrate the feasibility of the
drive beam generation with the appropriate time structure\, the extraction
of 30 GHz RF power from this beam\, as well as acceleration of a probe be
am with 30 GHz RF cavities. CTF3 is based on much of the former LEP Pre-In
jector (LPI) equipment and is constructed in several phases as new compone
nts become available.\n\nThe talk will present the drive beam generation s
cheme with a focus on the different key issues to be addressed in CTF3. It
will outline the different phases to reach the goals and will give a repo
rt of the status of the program. Some remarkable results of the present ph
ase will also be shown.\n\nhttp://indico.cern.ch/conferenceDisplay.py?conf

SUMMARY:The CTF3 Drive Beam Linac - Why and How?\n

DESCRIPTION:The drive beam of the CLIC two-beam scheme transports and stor
es energy in long\, high current electron pulses at a relatively modest be
am energy. Later temporal compression of the pulses\, accompanied with fre
quency multiplication (in the compressor rings) allows to provide - by mea
ns of the power extraction and transfer structures (PETS) - very high peak
power at 30 GHz necessary to accelerate the main beam. \nHence the CLIC d
rive beam linac must cope with high beam currents\, and as a major part of
the power generation scheme\, it must efficiently transfer power from RF
to beam. One of the goals of CTF3 is to demonstrate this with a drive lina
c operating at 3 GHz.\nThe high beam current requires strong damping of di
pole wake fields\, which is presently obtained by silicon carbide loads in
corporated in a novel type of structure called SICA (for 'slotted iris - c
onstant aperture'). The high RF to beam efficiency will be obtained by so-
called 'fully loaded' operation\, where the input power to an accelerating
section is equal to the beam power increase in this section. The talk wil
l explain these main features of the CTF3 drive linac in some detail and p
resent results measured on the recently built prototypes.Organiser(s): S.

DESCRIPTION:The 26th Advanced ICFA Beam Dynamics Workshop on 'Nanometre-Si
ze Colliding Beams' (Nanobeam2002) was held in Lausanne\, 2-6 September\,
2002. It was jointly organized by the University of Lausanne\, the EPFL\,
and CERN.\n\nAlmost 100 participants from 35 institutes used this opportun
ity to discuss the recent state of the art in producing and stabilizing na
nometre size beams. Such beams with small spot sizes and excellent stabili
ty are in particular required in any future linear collider project\, but
are also of interest for next generation synchrotron light sources. Associ
ated stability requirements can be addressed with technologies applied suc
cessfully in gravitational wave detectors or the semiconductor industry. T
he workshop provided a forum for the lively exchange of new ideas between
different communities\, which are all pushing the limits of technology.\n\
nThe topics discussed for possible collaboration included ground motion an
d vibration measurements\, active stabilization of magnets\, design and tu
ning of a demagnifying beam optics\, ultra-fast beam-based feedbacks\, pre
cision beam energy measurements\, laser wires\, other advanced beam diagno
stics\, low-emittance beam generation\, test facilities and future R&D.\n\
nHighlights and conclusions of the workshop are presented.Organiser(s): S.
