* 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
 +

**  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.

**** Low rate / large angle with N2 and LAPPD
 +
***** Access will be opportunistic, will need to repressurize.

**** 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.

 +
 
 +
*  Tank delivery estimate?
 +
**  Assuming 2-weeks from today (Jan 20th).  If we are ready sooner, we will deliver ASAP.
