Yes, Simon would be right. Please do the dump of ghost beams in that way.

Wide-Angle-Baffle

I made a simulation with my model calculating the strain on an OSEM magnet by assuming a slightly magnetized solblack coated Cylinder in 20cm distance vibrating with the Kamioka seismic noise. I call this "Model1". The result is attached to this report.

VB

I had a phone call with Steve from SNS about our maesurements on VB and the next steps.
Here are the main points:

1. They curently work on a new VB version which would be more stable against touching but this means also a higher reflectivity (first measurements at 2mum wavelengths show a 20 times higher value than the original VB) They are further try to work on this
2. For the original VB sample, he proposed a special covering of the parts with VB (namely the Doughnut-baffle) until the installation is done and a removal after the installation.
3. He will send me a cost estimation on the Doughnut-baffle by the end of next week
4. I also got information on the outgassing. It should be very low.
5. I will provide him our maximum budget for the Doughnut-baffle

Backscatterometer

There is maybe a problem with the ghost beams coming from the BS and hitting the Iris in front of the sample.
I am afraid that this will produce some additional scattering light which superpositions the backscatter-signal and disturb the measurements especially for wide angles.

Torii-san and I tried to set an obliqued ND filter in front of the Iris to remove the ghost beam hitting the surface of the Iris.
The first results seem to support my fears.
Estimated influence on photocurrent: 0.1 - 0.2 nA

How one can get the latest OSLogbook?

This is Prof. Hyung Won Lee at Inje University, Korea.
I want to install OSLogbook using for my lab.
my e-mail is hwlee@inje.ac.kr

After some research I find that Archaiomelesidonophrunicherata means "the good old honey-sweet songs from the Sidonian (play) of Phrynichus" - Aristophanes' "The Wasps" line 220.

I also prefer color other than blue or green.

Virgo logbook is also green. https://tds.ego-gw.it/itf/osl_virgo/

Test report

The sane in Maine are plainly on the wane.

Can we make the main color red or something? Green color looks like LLO alog to me. It is not that important though.
