- Tank and cradle is mostly finished.
- All BNC patch cables (150 8') are done, still need to finish ~30 SHV patch cables.
- Stand updates

PMT and LAPPD coating is finished.

Electronics update?
- Zhiwen tested the sum board, has ringing.

DAQ status?
- Computer for data storage?
- Analyzer?

Documentation

Monday, January 13th, 2020

Engineering status
- Updates on Tank Construction

Fig. 3: LAPPD box tests

Fig. 4: MaPMT box

- Updates on Stand Construction

Cabling update:
- About 100 8' BNC patch cables are done, still need to make 40-50 BNC and all the SHV:
- Do we need additional SHV patch for all scintillators and calorimeter PMTs. I have enough ends to make ~30 cables, but that will cover the MaPMTs + a few extras. I will need to order more SHV connectors if the lab doesn't have enough cables.
- Lemo cables? (DAQ side)

Mirrors update:
- We have everything, just need to assemble

Electronics board update:
- Have everything, sending the boards and 160 MCX connectors and PMT pin bases to JLab on Wednesday morning.
  - I need to find out how long it will take to have a board assembled.
  - Just ordered the LV cable (and connectors) needed to run up to 50'.

Tank delivery
- Still Monday the 20th?
  - A1 is running well now! d2 change over "unofficially" delayed by 2 weeks.
  - Electronics board and LV cable are the holding issues.

DAQ
- Are we ready to set up a cosmics DAQ
- Computer purchase?
- Analyzer programing?

Documentation for device
- Safety documentation for JLab
- Alignment, calibration, and commissioning procedures.
  - Lasers to align to beam-line.
- Heavy gas fill procedure
  - Environmental/safety issues with heavy gas purge?
- Run Plan
  - Tentative order:
    - Low rate / large angle with N2 and summing board
      - Access will be for install, will need to repressurize.
    - Low rate / large angle with N2 and LAPPD
      - Access will be opportunistic, will need to repressurize.
    - High rate / small angle with N2 and LAPPD
      - Access needed to switch to small angle.
    - High rate /small angle with N2 and summing board
      - Access will be opportunistic, will need to repressurize.
    - High rate /small angle with Heavy Gas and summing board
      - Access will be opportunistic, will need to flush and fill with heavy gas.
    - High rate /small angle with Heavy Gas and MAROC
      - Access will be opportunistic, will need to refill with heavy gas.
- Kinematics switch timeline/plan

Any A1/d2n scheduling updates?

Engineering status
- Updates on Tank Construction
  - New cradle design with 80/20:
    
    Fig. 1: 80/20 cradle design
  - LAPPD box has leaky BNC feed throughs. Not sure about MaPMT box.
- Updates on Stand Construction

Outstanding items that need to be ordered/built/procured
- Status of current orders:
  - MaPMTs (Ordered via ANL)
  - Mirrors (ECI film shipped, expected today/tomorrow)
    - Still need to do mirror assembly, i.e. attach film to carbon fiber blank. We have lexan film with no reflective coating to test.
  - Electronic summing board board (Ordered, board is printed and currently in component assembly)
    - Also will need to have MCX connectors attached (done at JLab, if Jack hasn't disowned us)
  - Gas regulation system (In hand, being assembled)
  - Cabling between prototype and patch-panel
    - Cabling (Components are in hand and set up to make 150 8' BNC patch cables and ~30 patch SHV, construction this week)
    - Do we have the additional SHV cables at the Lab?
  - Cabling between patch-panel and DAQ
    - Do we have the necessary BNC and SHV? Can we find the lemo cables? (Who to ask, Alex?)

Tank delivery estimate?
- Assuming 2-weeks from today (Jan 20th). If we are ready sooner, we will deliver ASAP.
  - I'll likely be delivering the tank to JLab alone, so I will need some help loading and unloading the van.

Preparation of Cosmics test.
- Space at the lab?
- Electronics and cables ready?
- Schedule for bench testing calorimeter blocks and scintillators.

Documentation for device
- Safety documentation for JLab
- Alignment, calibration, and commissioning procedures.
  - Lasers to align to beam-line.

Engineering status
- Updates on Tank Construction
- Updates on Stand Construction

Outstanding items that need to be ordered/built/procured
- Status of current orders:
  - MaPMTs (Need ordering institution)
  - Mirrors (ECI film ordered)
  - Electronic summing board board (Final quote determined, 2-week lead time)
  - Gas regulation system (ordered, still needs to be assembled)
    - What extra care do we need for gas tank, plumbing from tank on the floor to tank on table should bbe straight forward.
  - Cabling before patch-panel
    - What patch cables do we need? 134 BNC patch cables? Can we use cables from the previous prototype? How about SHV? Do we need 70 SHV patch cables also?
  - Cabling after patch-panel
    - Do we have the necessary BNC and SHV? Can we find the lemo cables? (Jian-Ping seems to think we can find the lemo cables at JLab)

Preparation of Cosmics test.
- Space at the lab?
- Electronics and cables ready?
- Schedule for bench testing calorimeter blocks and scintillators.
