(Toshiba, 1/4 cryostat, Sapphire fibers, ET meeting, Jena) Current status (Toshiba, 1/4 cryostat, Sapphire fibers, ET meeting, Jena) Kazuhiro Yamamoto Institute for Cosmic Ray Research The university of Tokyo KAGRA cryogenic payload meeting 12 December 2012 1

Toshiba 1/2 dummy payload with sapphire dummy mirror (Initial cooling time by radiation) Manufacturing started and is in progress. 2

1/4 cryostat Design and discussion for 1/4 cryostat to check payload is in progress. Bid (for parts) will be opened in this December. Preliminary. 3 3

Sapphire fibers Sapphire fibers with nail heads Ettore Majorana asked IMPEX HighTech GmbH (German company). They can make similar fibers (nail heads on the both ends). Finally ...

Sapphire fibers (c) Sapphire fibers with nail heads IMPEX fibers arrived ! (15th of Nov.) 5 5

Sapphire fibers Quality check Q-value and profile of Moltech fibers: Y. Sakakibara at Glasgow and Jena. Although they are broken, the measurement result is promising. Two Moltech fibers and two IMPEX fibers were sent to Jena (29th of Nov.).

Sapphire fibers Two Moltech fibers and two IMPEX fibers were sent to Jena (29th of Nov.). They survived ! (Photos from Jena)

ET meeting in Hannover 4th-5th Dec. 2012 http://et-meeting2012.aei.mpg.de/ Kazuhiro reported the current status of KAGRA cryogenic system. http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/DocDB/ShowDocument?docid=1407

Jena 6th-7th Dec. 2012 Kazuhiro visited Friedrich-Schiller-Universitaet Jena. Yusuke measured Q-values of sapphire fibers. http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=1420

Jena Nitric acid washing works well ! Before After

Jena 6th-7th Dec. 2012 Ronny, Christian, Ettore (skype from Rome), Yusuke, and Kazuhiro discussed the strategy. In Jena Q-value with other type clamps, Thermal conductivity, Unbroken Moltech fibers, IMPEX fibers, X-ray (crystal structure), impurity measurement Around March, these fibers will be sent to Rome and Ettore continue the investigation. 11

Jena 6th-7th Dec. 2012 Ronny, Christian, Ettore (skype from Rome), Yusuke, and Kazuhiro discussed the strategy. In Rome, Ettore ordered other IMPEX fibers (manufacturing procedure is different). They will arrive on the end of January. Q-measurement system in Jena could be exported to Japan. If possible, students and Post doc are exchanged.
