• About DoF sensors and normal sensors, and comparison with Optickle getTF function.

New noise budget and transfer functions are shown Lentickle wiki. We suspect that Optickle getTF and lentickle pickleTF calculate the TFs different way. In optickle, they take into account force-displacement conversion, but not in Lentickle (is my understanding correct?). We are going to validate the code.

The meeting was canceled after 10 mintes because of the internet disconnection due to an unexpected power shutdown at LLO

To do

• Upload the stuff to the cvs sever (Keiko)
• Double check of the codes (Nic / Kiwamu)
• Produce some correct noise budget / transfer functions (Keiko)

Lentickle tips

pickleTF(result, 'A', 'B', 'ol' ) ... TF from A to B without the control

Participants: Keiko, Anamaria, Jenne, Kiwamu, Nick

• Lentickle : Nick pointed out how to get the seismic noise budget (to add seismic motion to all the optics, and use the DoF defined sensor)

• Lentickle tip ... pickleTF(result, "mirr", "MICH") you can use a "DoF sensor." Using "mirr" returns the array of transfer function from all the drives to the sensor. <-- this didn't work. Nick is going to fix the code.

• RAM simulation

sensing matrix in the RAM case, signal offset levels will be evaluated. AM modulator will be put in Mach-Zehnder.

minutes

• C1 lentickle - OLT, laser frequency, amplitude noise TF, Seismic noise budget plots
• Nick corrected some points in cucumber script
• 40m OLT seems to be calculated correctly!

Participants: Keiko, Jenne, Kiwamu, Nick

C1 lentickle model update

• C1 cucumber is written (iscmodeling CVS, LentickleC1 folder)

• It runs OK. It is needed to be modified with the actual filter parameters and so on.
• Shall we develop the modal model too, with Finesse?

40m Lab update

• The corner MI has been locked
• However spikes in LSC signals are observed and being investigated

Participants: Keiko, Kiwamu, Jenne, Anamaria, and Nick

Jan 19 14PM CST

minuts

• Lentickle instruction from Nick and Jeff

• exampleMICH.m instruction

• cucmberMICH.m instruction

• LentickleALIGO (iscmodeling CVS) has an opt model for aLIGO, but not any lentickle script yet. The opt model didn't agree with Lisa's or Stefan's models in terms of DC field levels

Participants: Keiko, Jenne, Nick, and Jeff
