Participants: Simone Gerardin, Luca Bocchini, Giorgia Straface, Natalia Emriskova, Marta Bagatin, David Lucsanyi, Andreas Waets

Actions:

• (Simone: Organisation of a  dedicated WP5 meeting where device results can be shown, including UniPD and TESAT results. Please forward the invitation to the WP7 mailing list.)
• Natalia: Provide UniPD a transient from the diode for TCAD analysis
• Simone: share the details on the Geant4 physics lists used in simulations to David.
• David: Update the website for the WP3 composition (Claudio -> Giorgia).
• Andreas: Check with HEARTS project office if Deliverables 3.4 and 3.5 can be merged.
• Andreas: make "Step 1" results available to David for further simulation studies.
• Andreas: communicate on the drafting of the deliverable reports in September.

Intro & WP progress (Andreas):

• We should check if Alberto  can be added to the mailing list of WP7/WP5? Simone will organise a WP5 meeting since Alberto's test results fit well into the WP5 activities. The results will show HEARTS@CERN in comparison to HEARTS@GSI and other facilities. Also UniPDs results from HEARTS@CERN/HEARTS@GSI beam time can be shown.
• Luca mentions that Claudio Cipriani is replaced by Giorgia Straface -> contact David to update website
• Everything is well on track. No deliverables in 2026 doesn't mean the activities/tasks will stop.
• All deliverable and milestone reports were accepted. Comments were shared for information  from the Year 2 report.

Overview of Tasks 3.4 and 3.5 (Simone):

• Simone shows an overview of the achieved results to far. There should be no problem to complete the deliverable report(s) at the end of the year.
• Many tasks and results are applicable to both Deliverable 3.4 and 3.5. We can check with the project office if these two deliverables could be merged.
• When it comes to the LET uncertainty reduction: CERN can lead the effort of gathering all experimental and simulation assesments that determine the beam LET at test location. UniPD leads in terms of determination of LET uncertainty on device level. David's simulation work can complement this.
• The diode results from UniPD offer a good independent check of HEARTS beams, the comparison will be very valuable. Natalia can provide a transient to UniPD for TCAD analysis.
• Simone can share details on Geant4 physics lists in simulations to David who is interested.
• Natalia mentions that the histogram axes for the paremetric "Cubes" geometry could be made the same, allowing for a more direct comparison.
• The 3D NAND flash memory results show a qualitatively good comparison to the cubes simulation geometry despite a different SV size. This shows that the cubes simulation model offers good understanding of device response.

Update on CERN T8 beam line simulations:

• A vacuum chamber was installed in the first dipole magnet aperture, a bottleneck for improving the beam quality at CERN. Simulations will shed light on how much the beam energy can be lowered to rely less on degraders to achieve high LETs.
• Andreas can share the results of the "step 1" simulations to serve as input for David's Fluka 5 simulations.

Conclusion:

• A reminder and determination of an "internal deadline" for the D3.4/3.5 report will be communicated in September, along with a template report.
