----
 
 * Birefringence characterization paper presentation (S. Singh):

'Complete Birefringence and Jones matrix characterization using Arbitrary Polarization' to be submitted in Optics Express

Article will be circulated to MIR group

 * Sapphire spectroscopy (M. Eisenmann):

Currently upgrading spectrophotometer with polarizer to measure absorption spectrum with s-polarized light

Plan to measure all sapphire samples of NAOJ

In longer term will measure with p-pol aswell

 * Weigthed PDs (D. Haba)

Now writing Master thesis (in japanese but abstract will be in English)

Also computing inspiral range with new sensors

  * Visitors (H. Wang)
Carl Blair will come to Japan in 2 weeks to work part in KAGRA part in Tokyo

Possibility to have also visit of Australian students to work on birefringence

BNU student (Chenjie) will come for 1 year to work on birefringence compensation


  * Next meeting
ICRR inter-university report on January 29th..

Next meeting likely to be on February 4th
