[Halla_running] [Revised Logentry] Hall status update -- Tuesday

Logentry Text:

Beam to Hall D was restored during OWL this morning and they continued their
program.  Unfortunately the accumulated delays pushed beam to Hall A back
at least 1 more day.

So, it looks like no beam to Hall A until Friday at the earliest.

Shifts remain canceled through Thursday OWL as before.  Thursday DAY and
SWING, and Friday shift crew should watch their emails for updates.

A target cooldown is still planned for Thursday DAY.  If it succeeds then
target practical training *may* occur during Thursday SWING and possibly into
Friday DAY shift.  Target operators should stay tuned and make an effort to
attend if possible.

A classroom target training session is still planned for 1:30-3:30 on 11/6
(Thursday) in CEBEAF Center room B101.  Contact JP Chen <jpchen at jlab.org> if
you are a TO to get trained.  Note that you will probably need the practical
as well -- talk to JP or Greg Smith for details.

We will be having a meeting tomorrow (Wednesday) at 4pm in the Counting House.

----------------------
Plans (Tentative)
----------------------
- Wednesday:
  - DAQ stress test
    - ROC sync monitoring needed
    - use EDTM(?) to trigger both LHRS and Calorim at high rates
    - verify no bottlenecks in system:  ROCS-->DAQ--->Tape
    - test buffering mode

- Thursday:
  * suggest MCC do complete any remaining HCO items during DAY shift (avoid
    interference with target cooldown through)
    - ie. then MCC can do repairs on Friday day before final lock-up
  - target cool down (DAY shift)
  - target training (afternoon)
  * when/if warm target back up ?
    - one suggestion (discussed with Greg) is to warm up on Friday DAY 
      at the latest
    * that means solid targets /only/ over the weekend

- Friday:
  - RF separation work during OWL and DAY shift, possible beam in SWING
  ? warm up cryo target during DAY shift ?

----------------------------------------------------------
Punch list Items (accumulated from my notes + whiteboard)
----------------------------------------------------------
- "Bullet point" run plan for RC and shift crew
  - Some items are here:
    DVCS: https://hallaweb.jlab.org/wiki/index.php/Run_Plan_%28DVCS3%29
    GMp:  https://hallaweb.jlab.org/wiki/index.php/Commissioning_Run_Plan

- Online checklist for shift crew

- SuperHarps (Sue Whitherspoon, ???)
  - 5/6 working, we're missing hardware for the 6th
  - missing harp is just upstream of target (confirm)
  * need to have a commissioning plan that takes this into account, WHICH 5/6
    harps should be set up to work now
    - do we want to 'swap' the hardware to get the 6th working at some point and
      do a bulls-eye scan to calibrate the associated BPMs?

- BCMs (Luke)
  - confirm all BCMs are in data stream

- Unser status?

- Moller status (Roman on-site next week?)

- ARC energy equipment status?

- F1 TDC readout and decoding (Steve, Alex, Marco)
  - missing level translator module needed to feed some signals to F1s (Alex)
  - F1 decoding not in analyzer?  (Marco)

- Scaler setup
  - add Busy to 2nd scaler (Norman)
  - tests using artificial busy (Marco, Norman)

- Crate sync scalers and/or ADCs (Paul)

- "Add new decoding stuff into DVCS analyzer"  (Carlos)
  - not sure what this means

- Cosmics checkout questions  (Kijun, ???)
  - GMP trigger mode vs. DVCS trigger mode (not sure of the difference)

- Helicity signals (Buddhini, Alex)
  - signals plugged in, but not clear what the associated FB ADC channels are

- Logbook fixes (Brad)
  - I added some 'pre-filtered' lists under 'Useful Links'
    - let me know if there are others you want
  - send me your list of annoyances...

- New TCL/tk 'halog' utility (new logbook only)  (Brad)

- Firefox seems to be broken on adaq cluster?

- HRS angle snapshots into DAQ (Brad)
