Description

The Convenor for this working group is Dr. Brian Chase and the Scientific Secretary Dr. Edmond Ciapala.

The mini-oral presentations have been assigned to the different working groups, however the exact times of the presentations will be decided by the convenor at a later date. Note that oral presentations, 39,42,50 will be presented in a joint session with WG3. Again the convenors will decide the timetable for this.

39. Adaptive Resonance Control for LANSCE-R

Mr Sungil Kwon (LANL)

oral mini talk

Resonance control of the low level RF control of the linac accelerator system achieves the match between the driving RF frequency and the cavity resonance frequency, the match between the cavity resonance frequency and the linac design operating frequency. First of all, these matches are obtained by adjusting the driving RF frequency to the cavity resonance frequency. When the driving...

50. Software development for FPGA based cavity controller and simulator SIMCON

Mr Jaroslaw Szewinski (Institute of Electronic Systems Warsaw Univ of Technology / Deutsches Elektronen Synchrotron DESY), Mr Piotr Pucyk (Institute of Electronic Systems Warsaw Univ of Technology / Deutsches Elektronen Synchrotron DESY)

11/10/2005, 16:07

oral mini talk

The FPGA based cavity simulator and controller provides the features and performance which is unique in todays control devices used in LLRF system. The software which is provided for the hardware operation can be used also for algorithms development. It consists of two control enviroments DOOCS and Matlab based. The first one is dedicated for the regular device operation during the...

42. Vector Modulation of High RF Power using Ferrite Phase Shifters

Dr Yoon Kang (Oak Ridge National Laboratory)

12/10/2005, 16:00

oral mini talk

In generation and distribution of high power RF for charged particle accelerators, a fan-out configuration to power many cavities using a high powered klystron is considered advantageous in saving construction and installation cost. High power fast RF phase shifters can be used to construct a vector modulator for independent control of RF amplitude and phase delivered to an...
