Status of the Transfer of CRYRING to FAIR

Status of the Transfer of CRYRING to FAIR

MSL, 2 February 2009

•March 2008: Letter from FLAIR collaboration to FAIR and Swedish Research Council that FLAIR accepts CRYRING as the LSR.

• June 2008: Discussion between MSL and the Swedish Research Council, where it is agreed that MSL will obtain 30 MSEK to cover the costs of keeping the ring at MSL though 2010, make the necessary modifications, and transfer it to FAIR.

•February 2009: No contract yet between MSL and Swedish Research Council, mainly because of unclear rules about how FAIR is to accept in-kind contributions to experiments (my interpretation). Nevertheless MSL has started to spend the money.
