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.
• KC made the new algorithm without arc tangent. JGP will check the formulas with real data. KK will check if it can be done in the CDS system or not.
• 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).

10/6 skype telecon

• Target is Physical Letter A.
• We check the calibration again with the peak areas and higher harmonics taken into account.
• We check the drift data with the calibration factor.
• For paper, KK and SK will write the intro part, and JGP will write the resulting part.
