3. Minutes of last meeting

 

Approved.

 

 

4. Long term plans for the activities of NorduCLIC consortium to be summarize for the Nordic CERN Council delegates (see text below and documents attached)

 

Plan: to present to NorduCLIC Council delegates in December our common plans for this decade.   Should be sent to delegates before December 6, 2010.

 

 

Status of original NorduCLIC proposals:

 

Status part a) Design and radiofrequency (RF) simulations:

 

University of Oslo has hired new Ph.D. student (KS) that will work on the original part A), with the following modifications:

- not necessarily produce three subsequent designs

- instead focus as well on rf simulation for breakdown experiments, in cooperation with the rest of the NorduCLIC partners in the 12TS project.

- the code will not be HFSS, but the SLAC ACE3P code suite.

 

Details are found in the NorduCLIC document :

E. Adli, "Proposal for RF design and simulation tasks within the NorduCLIC framework", 2010

http://indico.cern.ch/getFile.py/access?contribId=1&resId=0&materialId=slides&confId=101008

 

 

Status part b) Fabrication:

 

- not been realized at all

- Helsinki proposal: had to be submitted before NorduCLIC application was finalized

- instead: the funded Finnish PhD student will focus on part c), in cooperation with Uppsala partners

 

 

 

Status of part c) instrumentation and experiments in the CLIC Experimental Area:

 

- Uppsala hired a post.doc. that will start the 1st of january, 2 years contract.  Person:  Marek J.  prev. nuclear Physics group at Uppsala

- spectroscopy: flash-box for particle spectroscopy (magnetic and electric field:  electrons on the other side, ions on one side) for the two-beam test stand 

- dynamic vaccum: for measuring vacuum as function of time might cooperate to Finland (via KO).  Will need mode-coupled laser  

- rf instrumentation: similar to TBTS rf instrumentation

- Marek will look into this

   - get Flash-Box for TBTS up and running, learn, then adapt  Flash-Box for 12TS (either make second one, or re-use the TBTS Flash-Box)

 

budget: probably not money for enough digitizers

- every digitizer is ~10000 EUR (~ 4 channels)

- would need ~4-5 digitizer

 

RR:

- would gain most by putting money into dynamic measurement

- rf equipment could maybe be borrowed/funded by CERN

 

Status 12TS:

- HV pulse modulator (solid state) from Scandinova has been delivered

- Klystron delivered from SLAC (originally one of the two foreseen from PSI), it had a "bumpy road", some effects, to be fully 

- control and LLRF by CERN well underway

RR: will probably take several months before any real equipment or structures can be installed in the 12TS 

12TS time-line: full Uppsala involvement at least for the period of Marek (start 2011 to end 2012)

 

TBM:

- KO: involved in TBM, design of structures

- mechanical simulations (heat, weight etc), working together with Germana

 

 

Status of current activites:

 

SS: we have 5 tasks already

a), b), c), + exploitation/operation + Aarhus activites

- we already have something that looks promising and ambitious to the council delegates, looks ok for Nordic meeting

TE: should we also push for increase?

SS: agrees with TE, difficult to say, not maybe at the meeting December 2010

- however, if we find something, especially with industral attraction, that would be good.

 

 

Going through list of Roberto Corsini to identify things of interest.  Items of interest :

 

* Operation with beam of a long string of CLIC two-beam modules, HW?, ***

* Build and test about 120 accelerating structures, HW, ***

* Four  12 GHz klystron-based RF high-power test stations, for about 8 slots,  running before 2016, HW, *

* Several nominal CLIC two-beam modules, mechanically tested, possibly beam tested, HW? 

* R&D and prototyping of critical beam instrumentation, HW

* Dynamic vacuum assessment, HW, 

* Improved cost model,  feedback to CLIC baseline review

* Beam physics studies

      (HW: Hardware)

 

comment EA: we should not feel bound to follow the list presented in detail, since it is only preliminary.  

 

Summarize: we present our current program up to 2012

- funding status

- status with respect to original program

- which items we can provide in the next period, up to 2016

 

Consensus that we all seem to be interested in the continuation of the the two-beam activites, including the TBMs, and explotation of the the CTF3+ with a long string of TBTs.

 

 

TE: will make a draft of text to be sent to delegates, and circulate it by November 23.

 

Norway: we need to submit our 2012-2016 proposal in May 2010

 

 

 

5. Report on progress in the CTF3 test program

 

[Postponed].

 

 

6. Date of next meeting

 

Monday, November 29, 2010, 13h-15h.

 

 

7. Any other business

 

None.
