Meeting

Note_First_Meeting

7/1 Skype Telecon

  • KC and JGP will consider closer for the optical configuration (please upload new info)
  • KK will check if we have all necessary components
  • KK, KC and JGP will discuss about the disital software in Seoul
  • SK and KK will meet in Kamioka for a preparation (8/10)
  • We'll have another skype meeting before the site work

7/8 in Sogang University

  • JGP will prepare the drawing of the configuration (on the pylon optical table)
  • JGP will prepare the required circuits (signal amps).
  • For the online data taking and analysis, we will need a digital model and MEDM screens. JGP will prepare the initial concept of the digital software.
  • With the prepared concept, we will build the model and make MEDM screens during KC/JGP visit (~1day).
  • We noticed that the digital software cannot do arc tangent. We will consider to use an approximation.
  • As planned, KK and SK will collect the necessary hardware on 8/10 (DC power supply, 50m cable, cable adaptors, AA filter)
  • KK will let JGP know about the Dsub 9 pin assignment to connect to an AA filter.

8/2 Skype Telecon

Preparation

  • JGP will get the drawing in a few days.
  • All the parts will arrive today. KC and JGP will carry them (no shipping).
  • JGP will assemble and test the circuits this week. Reports will be made next week.
  • Model and MEDM screens will be prepared with Kirii-kun on 8/10 as well as the first phase of the visit.
  • KC will think about the approximation formula of art tangent to use in the digital model.
  • SJ will submit the "tunnel entrance form" for the experiment.
  • KK will send the Dsub pin assignment today.
  • KK will find AA filter soon.

Other note

  • No IR laser beam during the experiment.
  • We have to check again about the safety lecture.

Next meeting

  • Next meeting will be 8/5 9:20 am. KK will call everyone on skype.

8/4 Skype telecon

  • The parts arrived; some mechanical parts were found wrong; JGP have fixed them; JGP will assemble today.
  • The drawing of the optical table (python table) will be done today by JGP.
  • Test result of the setup will be emailed.
  • KK will check KC's new algorithm and will let you know today.
  • Check the safety rule.
  • SJ will submit the mine entrance form.
  • JGP will carry the clumps (which is to fix the sensor on the table).
