3. Status of all experiments
Submissions since 2014
Another 9 experiments from 1st run in 2012

4. Limited pulse intensity since April 2016
Vacuum leak in SPS internal dump
Leak rate related to beam deposition
In view of LHC priority
Keep minimum risk from other SPS beams (FT, HRM)
HRM beam limited to a few ten bunches/pulse
E.g. no experiments with 50% of maximum intensity or higher
Excludes TCDI, RotColl, TDIcoat …
Still feasible in 2016: BTV2, ESScoat, dBM …
Spare is refurbished and ready for urgent intervention (not planned)
Shutdown 2016/17: new dump will be installed
Intensity limitations for 2017 are currently evaluated

7. USER DAY In the framework of the HiRadMat Scientific Board
Follow-up the scientific achievements from former experiments
Increase feed-back on facility implementation
Discussing the needs/improvements for the future use
Work shop at CERN, 28th June 2016

9. Technical wish list Hot cell for HRM users
Potentially in collaboration with PSI
Surface lab: full mock-up scenario of TNC/TT61+feed-throughs
Also reduces working hours in tunnel
Infrastructure for cryogenic experiments
Beam monitoring
3 units of BPKG/BTV available to experiments
Beam sigma measurement in the full range
Performance to be established/documented
Decouple HRM beam operation from LHC filling
Upgrading the power converters of the extraction line
Patch cabling TNC/TT61 (and fibre to HiRadMat control room)
Develop/identify common instrumentation
Decoupling the access to HRM from LHC filling does not justify the large costs needed. …

10. Support improvements
The support from all CERN groups to the HiRadMat users is highly appreciated.
Technical support for high-speed camera
Trained person available or dedicated training
Make sure that all beam monitoring is available and operational/logged.
Simpler access/provision of beam logging data
Improve registration for external users with full access to CERN (IT) infrastructure
15/9/2016
A. Fabich

11. Main activities until EYETS16/17
Evaluating possibilities for beam sigma measurement
Preparing to test cryogenic elements
Primarily using He dewars and a recuperation line
Studying technical layout
Investigating hazard/safety impact
15/9/2016
A. Fabich

12. Summary Limited HiRadMat performance in 2016
Still five experiments completed (mainly beam instrumentation)
Full recovery expected from 2017
Facility improvements, as discussed during HiRadMat User Days, under detailed study/preparation
2017 will be crowded. No serious spare slot available.

13. Agenda
HiRadMat overview
4 new proposals (each minutes):
CRY2
TDIcoat
FlexMat
MultiMat
HRM-TB reviewing in particular operational, safety and RP aspects of your experiment.  
Short overview of experimental layout (and latest updates). N.B.: The Board will have viewed your initial proposal submission.
Operational aspects including a beam pulse list
Safety: major safety aspects, a complete bill of materials, indication for use of special materials (toxic, flammable), handling procedures (before, during, after beam time), risk assessment
Radiation protection: expected activation, efforts for minimizing the activation, minimizing personnel dose, handling procedures, final disposal (if applicable)
Discussion/wrap-up

15. HRM facility layout and access
surface lab
Target area (TNC)
TT61
HRM CR
TI2
Access to HiRadMat
Only without extraction to TCC6 (=TI2 and HRM)
SPS can continue cycling.
Since 2014: TT61 is used for placing DAQ equipment only 10 m from the impact centre
Access coordinated with BE/OP, particularly in view of LHC operation
Often stand-by for access during several days
Great flexibility by RP and TRANSPORT (HE) is highly appreciated.

16. Access to V0-V7 V6 V0 BA7 HiRadMat ISR Muon pits of former WANF
Exposed to muon beam in forward direction of HiRadMat target area
Access to be restricted upon RP request
Access to VO needed about twice a year for intervention by CV
Skipping installation of full-fletched access control system (SPS)
Padlocks with manual veto system like in the North Area
Agreed by EN, BE and RP (EDMS )
Installed by BE/ICS
Manual veto held by EN/EA
Installation completed, operational from 2016
ISR

17. HiRadMat coordination
HiRadMat structure
Beam time application
Experiments are recommended by the HiRadMat Scientific Board
Scientific interest of the experiment, feasibility and post-irradiation analysis
Expected results and publications to the interest of the scientific community
Approval validated by the HiRadMat Technical Board
Integration, operational and safety aspects, radiation protection and waste management
So far we could assign beam time to all approved experiments
If a scheduling difficulty arises, HRM coordination
discusses with the experiments on scheduling flexibility
consults with Scientific Board comparing the technical/scientific urgency of the experiments
If no solution is found:
Prepare recommendation/report to IEFC and/or ATSMB
