Intro: 
- mid july review with cad snapshots of the current model


Tom:
- pair creation is ready!
- not yet depending on photon polarisation
- need to agree on the setup parameters for the collision - particularly the laser —> can be ready for mid July? yes (next week also) —> start email thread with Matt, Gianluca, et al
- mCP not done yet
- need volunteers to work on the HDF5 to ROOT converter —> David Spataro (will also talk with Sasha and Arka in view of git and Theia, etc).

Maryna:
- dump induced backgrounds
- which format of Tom’s MC are you reading?
- what would the neutron do to the lanex? (rad-hardness and fake signal?)
- need some clarification for slide 7 —> is there an energy cut? need to see what’s the threshold for the signal in the lanex (John: ~keV?)
- looks like we can use 80 cm concrete blocks (easily available) to replace the “metal wall”. 
- Louis:
  - how large should be the wall of shielding?
  - extend plots for the full dimensions of the wall
  - need to check the weight of a wall of concrete 
  - the pressure of 20 kN/m2 (2 Tons/m2) is the maximum allowed in the cavern. 
- Beate: we need the threshold 
- John:
  - vast majority of the neutrons will not make a signal
  - the radiation damage is much smaller than the e+e-/gamma.
  - energy threshold is extremely low since we’re creating optical photons in the screen… (10 keV photon has ~20% efficiency and 100 keV has an ~80% efficiency. Above 100 keV it is ~100% efficient)

Noam:
- check with Kyle if the aluminium is tolerant to the beam
- check what is the signal blob size in y axis - maybe we can reduce the size of the window by a bit

There are minutes attached to this event. Show them.
