slot size = 25 mm
RF Meas ; Decay Time (ns)
83 ns (average)
slot size = 25 mm
Summary Shipment schedule- #1SM S-band BPM will be sent to KEK in advance on 10th of September.- #2SM,3QM,4QM S-band BPMs will be scheduled to be sent on around18th of September.
Decay time (cold test) was improved from 31 ns to 83 ns in average (RF simulation (HFSS) = 99ns)
Tentative visiting schedule (KEK) to be discussed. - Sept. 15 ~ Sept. 19 (?) ; Hyoung Suk Kim- Oct. 2 ~ Oct. ?? (?) ; Hyoung Suk Kim, Aeyoung Heo
