* Updates VMM

** Working on L0 mode - Hall B planning to use

** Purchase for rad hard component for LHC : lpGBT and VTR+ and bPol 2.5 - for TDIS and SoLID - in queue for 14 months - letter of increase added because cost went up - increase quantity to have the SoLID ones - might be coming soon : lpGBT and bPol (2.5 -> 2.5 to 1.2) and bPol12 might come in a week - could make the radhard mezzanine - could use bPol for PRAD and SBS - can test and measure noise - 

** VTR+ later

** interface from benchtop supply: design complete - still not ordered - need to be careful of spike at start - could ramp the supply

** Hall B has untested VMM - wants to make a 4 chips prototype - one engineer will test the VMM - will use one eval board with socket to test chips 

** need to replace the desiccant for VMM

** SALSA : 50 MHz FADC -  

** MPD - new version - 

** Pixel chamber GEM  - different pixel size - ~ 100 k channels

** check with Paolo, new MPD 

** APV25 220nm process - SAMPA 120 ns - SALSA 65 nm - check if line still exist

* Status orders

** FADC ordered

** VTP ordered

** TI 

** SD

** VXS - 24 ordered need 8 more

** VETROC

* MRPC electronics

** NALU ASOC and AARDVARC 

** picoTDC 

** SAMPIC 

* TDIS 

** wirechamber - 1 ns 

**  SAMPA close to 2 ns with fitting of pulse at 20 MHz
