  1. 27Jan2010 SVD meeting Tsuboyama

  2. Korea DAQ meeting (1st day) • Nakao: • Trigger/clock information does not come from COPPER. They comes  an independent system. (I am sorry I may have misunderstood the mails between Markus and Wecek.) • The common trigger/clock distribution will not be convenient. The  reason will be explained when he comes back and also to  Krakow people. • Itoh: • The same data is transferred to CDAQ and PXD. The system  should be designed to have enough performance to send  to two destinations. • Ushiroda • The high-voltage side signal is transferred in the long cable.  please be careful about the insulation or HV leak. • The Belle structure just outside of Belle is very crowded.  It may not be so obvious to find • Can you adjust APV operation parameters?  My answer is "yes" they are all programmable. • (Probably by) Liu Zhen'An • What kind of connectors will be used? (I could not understand the question)

  3. Korea DAQ meeting (2nd day) There was a discussion about "sender" board of the unified link, slow control...  The back board which Wacek proposed could be a model of the sender card. Itohhas a big concern about sending data from SVD to both CDAQ and PXD. Usually this kind of connection causes degradation of performance. The backboard should be designed to avoid such a dead lock.

  4. Wild pig • On sunday, a wild pig invaded a KEK radiation safety area. I was preparing the slide in KEK and witnessed the pig. KEKannounced that someone estimated that it weighs 130 kg.
