Target Lab Main

This is main page for work in EEL Target Lab since 2010.

Current Activity

• 2013/09
  • PNMR test: at the corner of the target enclosure. It involves very low power signal detection and the risk is below the Code 1 level.
  • density measurement: redo the setup
  • laser test: testing new lasers

Agenda

Date and Location:  Mon 1:30PM room F227
Conference ID 432708674
Audio Dial: 1-888-2402560 (US or Canada only) (see all numbers) and enter the Conference ID
Desktop sharing https://bluejeans.com/432708674 (REMEMBER to turn off mic and speaker after join to avoid echo if you use phoneline for audio)

• meeting system "bluejeans" howto
  • Through a browser in a computer, you can do desktop sharing, audio if you have a mic and speaker, and video if you have a webcam, just go to the conference link above and join as guest
  • Phoneline should have better audio quality because it's not limited by network speed
  • For browser, we recommend firefox on mac,windows and linux. Note at the first time you use it, a plugin needs to be downloaded and installed. On linux, only plugin available is for 64bit firefox and you need to install it as root.
  • You can use bluejeans app on your mobile device to connect also after downloading it from your device's app store.
  • Test the system by going to link http://bluejeans.com/111
  • To host or schedule a meeting, you need jlab account, refer to https://cc.jlab.org/bluejeans
