PS Machine Report (B. Mikulec)

Overall good progress refining beams and following injector planning with beam setup.

  • Overall availability Thu 9am - Thu 9am: 93.5%
    • Main downtime due to 2 accesses on Monday to install foils for EAST and a POPS DC/DC3 communication issue Tuesday night
  • EAST: extraction and transfer line optimisation ongoing (Eliott, Marc)
  • AD 5-bunch beam set up for FTA line commissioning next week
  • Delivering beams for SPS scrubbing, including 8b4e
  • AWAKE beam setup started
  • TOF: commissioning of refined FTN line optics (Yann) started successfully, but stopped, as the horizontal profile of the Semgrid in front of the target is not usable for high intensities. Spent yesterday to understand the issue with BI. We require an access today from 12:30-14:30 to exchange a patch panel to try to restore the situation from last year (issue also blocking for start of physics planned for next week).

n_TOF (Please Add Your Name Here)

First physics experiments with commissioning beam:

  • TOF imaging with novel detector
  • Diamond detector at NEAR (1e12 n/cm2/s) for flux characterization

General preparations for upcoming physics experiments.

Issue with the target’s SEM grid, to be investigated by OP/BI.

East Area Beam Status (D. Banerjee)

All beamlines have been successfully commissioned and ready for physics. Successful tests for monitoring the position of the beam on target done. Implementation being discussed with BE-OP. Installation of PAN in T09 is scheduled for today.

T8: IRRAD / CHARM (F. Ravotti)

The T8 beam setup and steering by BE-OP and SY-ABT continue also this week (see detials in PS report). On monday April 3rd we performed an intensity calibration run with metal activation foils, using slow- and fast-estracted beams both at the PS extraction region (F61) and at the end of the T8 line (see picture below). Short accesses to our irradiation areas on Monday evening and Wednesday afternoon (~1h) to start preparing for more detailed calibration/dosimetry measurements in IRRAD/CHARM next week. Work on beam continue until this evening aimimg to begin the irradiation of a batch of pasive samples in IRRAD during the Easter Weekend. Active irradiation experiments in IRRAD and CHARM scheduled to start in the coming weeks.

AWAKE (Giovanni Zevi Della Porta)

Preparing for proton run stating May 1st. New Discharge Plasma Source (DPS) transported to tunnel, installed and aligned. DPS commissioning ongoing. Electron beam commissioning whenever DPS team is not in the tunnel.

North Area Beam Status

Hardware commissioning close to being finished, polarity checks done. DSO tests on-going. Calibration of target beam intensity monitors scheduled for April 17th.

H8: MADMAX (Pascal Pralavorio)

The magnet is at 1.6 T since Friday 24-mar 12:00 in very stable conditions. Long run taken with the CB100 MADMAX Prototype booster at warm continue to proceed smoothly. Plan is to continue up to Friday 14-Apr and then dismount the set-up. The first test of a booster at cold, originally foreseen 14-19 april, is postponed to next year because a set-up adjustement is needed. This follows the conclusion from the preparatory cold test done in the cryolab last week.
