Minutes

Present: Elliott W, Josh B, Hovanes E, David L, Scot S, Mark S.


Equipment

  • Mark ordered two meters and an oscilloscope with FY11 money.
  • We have additional money in FY12 for test equipment.
  • Mark and Scot will propose an order for rack hardware, Ethernet power strips, etc, needs to be in by 1-Oct.


Test Lab

  • We need to be out by 1-Oct according to the nominal schedule.
  • Sarin and Scot worked on the Danfysik power supply. Sarin understands the slow dump mechanism and he and Scot verified it is working. The problem was when we went to a smaller dump resistor another part of the circuit needed modification. They found it worked with the nominal dump resistor.


Solenoid Control System

  • A subgroup (Elliott, Mark, Josh, Scot) will meet regularly to design the new system based on experience in the Test Lab.

  • Some equipement in the Test Lab will be moved to the test stand.
  • Hovanes is testing some new EPICS utilities, more need to be tested.
  • Ongoing/upcoming projects include FCAL bases and CAEN/Wiener crate control.


Nerses G

  • He will likely work on both low-level EPICS drivers, crate control, as well as high-level EPICS utilities.
  • Elliott noted that the new EPICS Java framework might be interesting, he will find out the latest on this.


Target

  • Control system needed by Summer 2012.
  • Should be easy, all control loops will likely reside in manufacturer hardware.
  • All we need to do is download setpoints and monitor health.
