Draft Budget request 2013 Schedule 2013 Experimental Program Draft Budget request Overall financial situation
Schedule 2013 • Start the repair of the helium gas leak from the cryogenics cooling circuit on top of the MFB • 2012 - losing 60m3/day of cold 4He gas – the escaping gas mostly recovered to balloons) • Open the MRB end of the cryostat & slide back the large MFB bellows • Thanks to TE-CRG • Separate the 3He gas lines from the cold bore • Remove the x-ray cold windows • Replace with open flanges linking cold bore vacuum to detector lines • Add new temperature probes to improve magnet temperature monitoring • Strengthen welding of XRT platform to accommodate new heavy shielding • Thanks to EN-MME • Dismount definitively the pn-CCD detector • Close up the cryostat • Pump down cryostat - 10 days ago • Some small leaks but eventually cured without reopening • Thanks Jean-Michel Laurent (TE-VSC retired) Today !
Schedule (cont) • Complete mechanical repairs on cryogenic compressors (TE-CRG) – vibration problems • Dismount the MPE XRT and send to PANTER for calibration • Cool magnet- mid July • Test magnet 13kA , then magnet temperature systematics tests (new temp probes) • Install new SRMM detector and new heavy shielding • Install Low Energy detector(s) on vacant beam port • Full survey GRID measurement (counterweights to simulate loading when data taking) • 3-4 weeks Solar tracking (tests & or data taking) with Low Energy detector(s) and SRMM (also SSMM (S5)) • Reinstall MPE XRT • Realign XRT with laser • Install new InGrid detector on XRT and align both together • Commission InGrid and also install the SSMM with new VETO counter at the other end • Commission all detectors • Short data taking run in November • (The new XRT from LLNL will not be installed in 2013)
Draft Budget Request 2013 • Budget to fulfil schedule above • Reduced from 355 kCHF(in Add No4) to 301 kCHF • In order to take account of changes in planning • Calibration of existing XRT late in the year • No installation of new XRT in 2013 • Reduced data taking period • Less subsistence required • In 2012, the expenditure was very similar ………at 296 kCHF • Detailed budget request over-page (compare to Add No4 )
Overall Financial Situation • Addendum No 4 signing phase - ~ 60% Institutes have signed • (see overpage) • Only 59.5 kCHFin Cash Contributions in 2013 so far due to late completion of Add No 4 • At the end of 2013 with no further Contributions to the Common Fund… • Balance will be -116 kCHF • We will come back to this in the financial outlook for Phase IV

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-keVPhysics) • 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
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
Completing Add No 4 ……… • …..feels to me at least, • a little like the punishment of Sisyphus • All Institutes are urged to: • Complete the signing of Add No 4 • Remove this obstacle, • Start sending in contributions • Both past & present • Let the Physics Program begin • Properly funded and supported Add No4
Greek Delegation Contributions - history • At present date: • Contributions for 2012 (150kCHF) and 2013 (150kCHF) are outstanding
Completing Add No 4 – felt like …… • ………the punishment of Sisyphus • All Institutes are urged to: • Complete the signing of Add No 4 • Start sending in Contributions (past & present ) • So that the Physics Program • Can be well funded and supported • Add • No4
