Agenda

Schedule

Long Term Schedule: Gantt (Outstanding tasks)

8/9/21 Start Hot Check-out
8/16/21 Start commissioning (2 weeks)
8/23 BNNT cooldown in CMTF
8/30/21 Perform experiment (2 weeks)
10/18 C50R in CMTF
Booster qualification following experiment until cryo trade to CMTF

New items for discussion:

General:

Reports by Group:

Experiment:

COO/ESAD/RSAD prepared; committee response delivered. ERR walk-through yesterday.

CIS/EGG:

Gun operating at 180kV w/o Field Emission following rebuild, HV conditioning, and Kr processing (Many thanks to all involved!!)
Y-dipole interlock unbypassed in Glassman HVPS. Resistor tank removed; gun cabled directly to HVPS.
Gun HVPS locked out , reconnect gun valve, charge NF3, degas heater/puck, get UITF laser on (8/4)

Puck 8 moved to prep, heated, and de-gased. Some inhomogeneities observed. Puck heated and activated with low QE; laser alignment today.
Puck 18 to chamber for rough drive laser alignment.

Gun bake pump hi-potted.

Make photocathode (8/5) [Joe/Max]
Align laser to photocathode, using retro and QE (8/5) [Shukui]
Gun rebuild wiki

Old insulator (punctured) & Old puck manipulator/schneedle for reference; both replaced. Very modest SF6 leak id-ed on top of HV tank; will repair when practical.

DC Power:

Trims:
1. Trim magnets near gun re-cabled.
2. Wastewater beam line trims cabled up.
3. Trim magnets near FC#3: 401H/V (completed) & 501H/V correctors + 501 quad. Many polarity checks completed. 501 correctors re-designated
Former PEPPo solenoid repaired, mapped, and installed.
Solenoid PS being installed. Supply placed, cables pulled, cabled, and LCW hooked up.
MHB magnet re-designation to MLH to avoid confusion: Chris Gould making nomenclature changes / Gary Croke & Michele Joyce making controls changes / Eric Forman to update Quick Reference Drawing / Shaun to take care of song sheets
Changes made in UED workspace for names and field maps; ready to merge soon. (Thanks Gary/Michele!)
Replacement of cards and utility chassis' acquired for CEBAF under way...

Instrumentation and Controls:

Viewer system status [IC; Norris/Vennekate/McCaughan]

Recable 2 viewers in keV whose channels & hardware were appropriated for HDice (done)
Reconnect IYGM401 insertion depth adjusted
ITVM703 limit switch requires attachment; 800-line viewers non-communicating.
Brian Freeman available for adViewer work for video camera for ITVM604A? Dome focusing still required...

Wire Scanners [Delacruz/Poelker]

Harps all pass signal injection and stroke.

Chopper Controls (Windham/Lu)

Target Motion Control - Carriage remotely operable, step count needs some fine tuning.
Control Screen complete?

BPMs (Windham / Hesse / McCaughan)

Re-label IOCs/BPMs locally.

Faraday Cups / Picoammeters (Francis)

FC2 unlocked for HCO
Connections removed for shielding installation per RCG.
Picoammeters all good - some screen work required.

Vacuum (Ketchum/Kortze)

VBVM501 & VBVM602 slow valve connections. VBVM602 is new installation.
VFVM401 Fast Valve limit switches adjusted; Kortze working firmware
VCGM604 Cathode Gauge cabled
NEG on MeV spectrometer line reactivated.
VIPM301A/B hi-potted.

BCM

BCM project software integration under way between Musson/Seaton and Sue Witherspoon

RF/Cryo:

Booster at 2K and full
Laser RF HCO

SSG:

BLM installation underway:

Replace those previously removed
Additions
1. In crotch of MeV/Wastewater selecting dipole.
2. Near 1st new diagnostic cross d.s. of solenoid
3. Near 2nd new diagnostic cross by FC4
4. D.S. of target after lead shielding

FSD inputs (original)

Target motion (now software interlock)
Solenoid (Now engineered control)
BCM current clamp system
Update gold masking

ME / Installation:

Pb stacked; RCG required modification due to permanent shielding req delay.
New designs for FC3 and FC4 with a great many thanks to Shaun for the design work and John/Xi for Pb arrangement and table construction!
Songsheet being updated by Shaun; be sure to let him know when changes are made!
Permanent shielding purchase in progress - FML (Russ) for most current details
Unistrut mounting for cables when available
Mount gas bottle rack in Labyrinth (Staged); remove gas bottles to rack.

Sys Admin:

4th terminal system in Control room under assembled/rebuilt
Wall server configured
Need to configure wall monitors and install small networked printer.
