Future Outlook – Vacuum Running Experimental Program - Phase IV Financial Outlook for Phase IV

Experimental Program - Phase IV 2013 XRT support platform Strengthened to accept the 750kg of extra shielding.  New detectors & Upgrades: New SRMM, culmination of a long development for CAST – perhaps nearing the ultimate background levels for this type of detector on CAST. Small delays in construction but will be installed and ready by end August 2013 InGrid detector with outstanding potential both at sub-keV and keV energies, will need extensive commissioning as the CAST environment is hostile compared to the laboratory. Integration with the safety interlocks of XRT vacuum system is non-trivial. 2013 will be mainly for commissioning. The SSMM will have a quasi-complete veto counter coverage - which should bring the background down to the effective minimum for this generation of MM and better than the existing XRT-pnCCD.

Experimental Program - Phase IV Optics The existing MPE- XRT will be recalibrated at PANTER down to low energies (necessary for sub-keV Physics) It was unfortunate that the access to PANTER is late in 2013 but we are very fortunate to have any access at all in 2013 (thanks to H Brauninger). MPE-XRT ready for alignment in CAST by early October 2013. Then together with InGrid for a new campaign of measurements .  CAST foresees operating with 2 XRT’s for the first time but the new XRT for the SR side is now not due in CAST until mid-2014  In view of the changes to the delivery times of Detectors and Optics: CAST will adjust the schedule to maximise the time to test and commission detectors whilst awaiting the final complement of detectors and Optics. In particular, CAST intends to exploit the month of September 2013 for first LE tests & data taking Test one or more sub-keV detectors using the vacant beam ports of CAST whilst the XRT is calibrated. This will provide a first look in the sub-keV range. Candidates for these tests include a SDD detector and the InGrid if ready, In parallel the new SRMM (and perhaps the SSMM) can be commissioned in realistic conditions.  

Experimental Program - Phase IV CAST in 2014 The final schedule for the year 2014 depends on the new XRT calibration (and LE test runs and data taking in 2013) Currently, XRT calibration scheduled for May-June 2014. We will try to advance it.  5-7 months data taking should be possible (but only 3 months with the new XRT). Which is to be compared with 9 months planned for the axion physics in Phase IV of CAST. This may therefore necessitate a future request for further running in 2015. 2014 will be a very heavy year for CAST LS1

Financial Outlook for Phase IV First consider the contribution so far in 2013 Estimated extra spending to end 2013 ~ (170kCHF +19.4kCHF commitments) To restore CAST finances back to our model of 100kCHF buffer at the end of 2013: Need Additional Contributions of 215.8 kCHF CAST should be able to an achieved this easily with: Either the Outstanding Contributions from end 2012: Outstanding Contributions (OC) start of 2013 303.3k CHF OC on 11.06.13 (now repayments by GD(25k) and UZ(10k)) 268.3 kCHF Or Total Contributions still outstanding from the year 2013 ~ 280 kCHF Date Institute Income (kCHF) Comments   08.02.2013 Greek Delegation 25.0 [2011] Now 2011 paid 100/100kCHF 18.02.2013 MPP 5.0 [2013] (2012 will be paid) 21.02.2013 TUD 3.32 [2013] 05.03.2013 U. Bonn 20.0 [2012 & 2013] 27.05.2013 U. Patras 3.73 2.49 Total 59.55

Conclusions CAST has accumulated some delays in the quite ambitious transformation into Phase IV 2013 will be largely commissioning new or upgraded systems with a few weeks –> 1 month axion/LE data taking possible November/December. There could also be 3-4 weeks of ‘first look’ at the sub-keV region in September At the end of 2013 CAST will have 3 out of 4 beam-lines fully commissioned In 2014 we will take data on Axions and Chameleons awaiting the arrival of a second XRT After its integration we will have 3 or more months data taking with the full complement of detectors. We had planned for 9 months. In order to make this possible….. Add No 4 needs to be pushed to completion
