JInventory system and barcode scanner

  • Hovanes suggested adding two new fields, MAC_Address and IPName. Elliott will do this. The Telecom field will stay.
  • Wired barcodes scanners around $300, full-function wireless around $1600 or more.
  • Elliott will find out about Bluetooth versions.
  • Consensus is that we need at least two, one wired, one wireless.
  • Will purchase wired model now, not sure whether to buy wireless model now or later.
  • Consensus to enter slots as full items in the JInventory system.
  • Elliott will create scripts to automate creation of slot entries for crates.


Small UPS's

  • Still not clear how much power needed. We know what out equipment needs, not sure about other systems (e.g. SiPM cooling).
  • Hovanes found high-capacity expensive FCC Class B UPS's at Grainger. Low-capacity ones are easy to find.
  • Elliott asked Paul Powers to look into filtering Class A power down to Class B specs.
  • We believe our power factors are typically near one, maybe 0.9.


EPICS

  • Vanik continues to make progress on the stepper motor controller. He got the optical counter feature to work.
  • Will likely need optical limit switches since "home" feature not working well. Unfortunately they are easily radiation damaged.
  • UConn boards may be redesigned.
  • We're hoping Accelerator will take over four of our five power supplies (not the Solenoid supply).
