Description

Hi Brian,

The HWR LLRF trig device is P:HLRFTD,W,E. There are cables pulled to rack 202. If you need 4, the cable numbers are 2105-2108 (HLRFT1-T4). They are terminated on our end but not plugged in because they are not terminated at rack 202. I think there are cable labels somewhere in rack 202.

The page with HWR pulse mode timing parameters is attached. In CW mode, the RF gate, Interlock permit gate, and LLRF trigger go static high. P:HRFMOD is the device that will alarm if pulse mode is selected.

Currently the triggers reference event $AD which is fixed 10Hz. Other options are $AA (fixed 1Hz), or $AF (fixed 20Hz).

Regards,
Mike

The four cables, 2105-2108 (HLRFT1-T4), were terminated with BNC's and then used 4 BNC to SMA jumpers to connect to the 4 SOC_MFC Controllers TTL Trig. I notified Mike Kucera that the job was complete, and he connected the cable on his end and reported all was good.
