Samuel Fazel described the DC cabling works expected during next YETS, for RMSES to Crome project, for TELMAX exp area, EPC power converters and BI equipment. These will take place between 27/01 and 21/02, in bdgs 93,193, 196, 370. Ac cabling expected also in 193 in the converters room.

Attention is drawn to the delicate area near the ELENA ion source. Also coactivity should be avoided with the source maintenance planned 08/01 till 21/01.

Mickael Lonjon introduced the works planned on newly installed switchboards. Most of these works were planned to take place before the YETS as had been agreed with the AD coordination, but due to the late delivery of some components, these will take place during the YETS. Affected systems will mostly be lighting, general usage plugs, including in the control room. In principle, the power supplies of the experimental areas are not concerned. As some very delicate computers are connected in GBAR, tests will be performed the day before the AUG tests (10^th January) to check the plugs concerned. Same for ASACUSA platform plugs. It is also requested to plan the intervention affecting the control room before the restart of the IST’s of ELENA systems (07^th February).

Nancy Paul showed the ongoing work taking place currently in the new TELMAX test beam area. The PAX experiment aims at probing the strong field QED with antiproto9nic atoms and quantum sensors. The setup being tested in TELMAX aims at testing the principle using Germanium detector, providing reference measurement before the TES (Transition Edge Sensor) detector is taken to CERN next year, that will be calibrated in parallel with the Germanium detector. The PAX setup was installed on the TELMAX beam in 3 days, and after bake-out reached 2.10E-9 mbar and was able to take first beams on 30^th October, testing at this occasion the new Multi Mini Bunch ELENA extraction mode. The first results are very encouraging, will allow to characterize the multi low-density bunches in TELMAX (intensity, length) and determine optional beam settings with Ge detector (solid angle and stopping power similar to TES). Nancy thanked all those involved in helping the setting-up of this new project on ELENA lines in a record time.

Davide Gamba gave a presentation on the considered future of our Antimatter facility. The current program at AD/ELENA is officially approved till LS4, but existing experiments and candidates have been asked by SPSC to provide by May 2025 proposals for future projects, specifying the required beam characteristics.  The European Strategy committee also invited new proposals to be expressed so that they can be taken in to consideration in the recommendations that will be formulated in 2026.

There are several possibilities for the future of AD, ranging from an end of the program after LS4 (unlikely) to a major improvement program allowing new physics possibilities with slow extraction at low and high energies, antideuteron production optimization etc.

The future will mostly depend on the physics programs proposed and retained. The question of the possible increase in ELENA beam intensity was asked. Davide answers that an increase by a factor up to 2 could be possible with careful studies/tests/settings of the AD + ELENA machines. In the current situation, bunches with up to 4 times more pbars can sporadically be delivered to experiments for test purpose, by generating only 1 bunch in ELENA instead of 4. Also stacking has been tested in AD in the past and proven to work, although the beam quality will surely suffer from space charge increase.

AOB: due to availability of resources in TE-VSC, the baking of AD sector 2B will have to be delayed by 2 weeks. As this activity is on the critical path,  it will cause a delay in physics restart of about 10 days (2^nd of May instead of 25^th April). This will be brought to IEFC.

Next meeting is scheduled for 28^th November 14h, when detailed YETS planning will be reviewed. AD experiments will be required to also show their YETS planning.
