The X-IFU Gazette #9

EDITORIAL September was a rather busy month for X-IFU. Following the X-IFU Consortium meeting #8 held in Geneva on the second week, the Athena bi-annual conference took place in Palermo on the fourth week. It was the opportunity to present the X-IFU progresses to the community and see in return how the community gets prepared to do science with X-IFU. Several talks highlighted the revolutionary potential of the X-IFU in many science corners of high-energy astrophysics. In the same month, we had to prepare the Instrument Consortia Consolidation (ICC) data pack, to be delivered to ESA on October 1st. The ICC is a rather light process led by ESA by which we expect the two instrument consortia to be formally recognized and appointed. This is an exercise focused mostly on programmatic issues, to ensure that the Athena Lead Funding Agencies (LFAs) are ready to support the overall Athena study phase and related activities (e.g. technology demonstration) until mission adoption. Following the data pack delivery, on October 5th, the ESA executives discussed the content of the ICC data pack with the Athena LFAs. As a very positive outcome, all X-IFU LFAs confirmed to ESA that they are ready to sign letter of endorsement for their proposed contribution. The whole process should be concluded by the next November ESA Science Program Committee. In parallel to the above activities, the CNES project team is consolidating the new Dewar baseline configuration to be submitted to the Instrument Preliminary Requirement Review (I-PRR) (see Alice contribution). On the programmatic front, ESA, JAXA, CNES and IRAP decided jointly to baseline JAXA as the provider of the 2K Joule-Thomson coolers. Finally the whole consortium is now focusing on writing documentation for the IPRR, which is expected to kick-off early February (see Thien contribution).
