1. Major subjects are listed below;
KNU (S. Jang) :
design of reference cavity - aperture, tuning method of frequency
simulation of DAQ with 100MHz digitizer (SIS3301) and integrated ADCs
plan of resolution study at IP
wakefield estimation - location of the reference cavity
in collaboration with A.Lyapin et al.
LAL :
test of piezo movers (BPM1&2)
- PI mover (BPM3) was tested
relative stability between two movers, i.e. between BPM1&2 and BPM3
(update) shipment plan of the IP-chambers
FONT :
performance study (IP-feedback)
definition of inputs for the IP-feedback
KEK :
preparation of flanges with feedthrous
scheduling the installation and any hardware updates if needed
2. Suggestions
(1) 9+1 inputs for the IP-feedback (slide-4)
(2) 2 optimum configurations, where the new IP is IPBPM-B or IPBPM-C
(3) wakefied effects were estimated by two methods,
i.e. Collimator and K.Bane's calculation
(4) the wakefield estimation prefers the IP at IPBPM-B and a taper
structure in front of IPBPM-A to reduce its effect further.
