IHA3H07B - harp damaged

6 hours 59 minutes ago
Log Number: 4475902Logbook(s): Body: 

The harp mechanical assembly and wire are damaged. The encoder case and connector is broken. The carriage will not insert when turning by hand, possible hardware and alignment issues. The harp wires are also broken (see photos attached).

Fopt - I&C test

7 hours 28 minutes ago
Log Number: 4475899Logbook(s): Tags: Body: Fopt 7.9 completed successfully. The runtime settings include a sample count of 15, a minimum current of 0, and an operating regime of Standard with Excitation in Injector. The corrector and RF kicks applied were 0.161198 and 0.230722 volts respectively. The files for this run were saved in the directory /cs/opshome/hlapps/optics/diforb/26mar120823. The X and Y stability of the machine during the run was 0 and 0 (mm) respectively.

Successful NL LEM at 1060

8 hours 14 minutes ago
Log Number: 4475887Logbook(s): Entry Makers: deirBody: 

With about 7 trips per shift and 450 uA linac current. 450 uA is a bit high for the upcoming 1060 run considering Hall A will be offline, so the predicted trips/shift will decrease a bit.

We have potential gains in 1L06 of 8.5 MeV (de-rated for heat load pending SRF input and Q0 updates) and in 1L12 of 2.8 MeV, see linked ELOG.

Fig 1: If we recover 1L04-6 & 7 that's another 11.95 MeV.

At a first glance, that's a total potential gain of 23.25 MeV.

Previous ODVH & Comments for 1L06 & 1L12

8 hours 30 minutes ago
Log Number: 4475884Logbook(s): Entry Makers: deirBody: 

Figs 1&2: Prior to changes to LEM NL at 1060.

Can change these back tomorrow night depending on SRF input.

Limited 1L12-3,7,8 due to WG Vac. Can raise them after they sit at these gradients for a day or so.

Figs 3 & 4: As is for 1L06 and 1L12.
