Minutes

Attendees: David L., Mark D., Mark I., Elton S., Rory M.

  • Meeting time and video conferencing
    • We agreed that the 4:00pm time every other Tuesday worked for now and so we will keep it.
    • Mark D. would like to have the meetings added to his Zimbra calendar (David will do it)
    • ESNet and ReadyTalk will be going away by the end of the fiscal year. JLab will be adopting Blue Jeans but JLab IT is still testing it
    • Rory and Dave will try Google Hangouts next week since Rory will be on travel for the next meeting
  • Reinforcement of the downstream platform
    • The downstream platform will hold the μ/π detector which contains a lot of iron and therefore weighs a lot
    • The platform will need to be reinforced to hold this additional weight.
    • An engineering student (Bobby Smythe) is working with Tim on this. He will give a presentation at a meeting soon.
  • MWPC Updated
    • Rory has 3 students working on different aspects of the MWPC design
    • Current guesstimate is that it will cost around $10/channel for the electronics. This includes a pre-amp integrated directly onto the PCB that holds the wires themselves.
    • They will be building a 6"x6" prototype chamber using frames created by a 3D printer in the UMass physics department.
