Data TakingData Taking
Change the NELM / Record and examine CC/NET-EPICS DAQ performance test
16ch ADC x 23 slot = 368 data / CAMAC module368 data / waveform is not reasonable.
64 data / Profile monitor4 data / Halo monitor4 data / Loss monitor
64 data is reasonable

CCR, MLFEPICS IOC
In the channel access between EPICS IOC to EPICS IOC,we got data missing.
As a cause of data missing, I expect Linux tick frequency.Default tick frequency is 100 Hz.DAQ frequency is 25 Hz.These are near in order.
Change Linux tick 1000 HzCompare Data missing ratio

CA performance is a little bit improved.
This CA result is not perfect but enough for monitoring with I/O display

Profile Monitor Test in KEKProfile Monitor Test in KEK
3NBT line transports 1 MW power proton beam, we have
to develop long life profile monitor.
SiC wire type profile monitor is developed.
Profile monitor performance is tested in KEK proton bea
m dump line.

SummarySummary
・ EPICS for 3NBT control system is under construction ・ Data archive at 25Hz from CAMAC-CC/NET to Channel archiver on Linux WS is successful, but data transport among EPICS IOC has still data missing.
・ 25Hz DAQ data taking becomes better with changing the linux tick to 1000Hz.
・ SiC wire proton beam profile monitor test was succeeded.

Future planFuture plan
・ Improve the EPICS data missing problem.
・ PLC (FA-M3) data I/O operation test.
・ Design 3NBT OPI display.
・ Design and test the DAQ and data archive system with full
scale system.
