Magnets?

 

Sasha:

- many updates

- straits were removed? we should have rail of scaffolding along the experiment

- what is the rates at the lower part of the tracker?

- the hexapod cannot travel 15 cm

- calice will be too high? —> elx can go sideway —> Halina will check with Romain (simulation, etc.)

- add a magnet in the end of the exp + dummy detector?

- need to decide about movement in x-z

- maybe we need to travel >20 cm up down

- need to add the services to the tracker and calo

 

John:

- make the stage much smaller

- need to check 

- can the camera be positioned in the front of the screen?

- table and supports will be the same as for the IP detectors (positron side)

- check the option to move the cameras to the front of the screen and lowering themas much as possible to the screen level (easier reconstruction)

- fine-tuning of the positioning will be done after benchmarking the model and running a small scale production (sig and bkg).

- need alignment for the cameras? what’s the tolerance 

- need a fast simulation of the camera response 

- need optical background simulation? take a picture where there’s no beam/laser

 

Maryna:

- why is the triangular chamber larger than the face of the detectors?

- can the profiler be just behind the screens? —> probably yes but need to study.

- need to check if 2cm diameter would be possible technically

- what are the electrons which are produced seemingly inside the triangular chamber? —> maybe make the triangular larger in y-axis.

- slides 9,10: what kind of window is assumed for the vacuum chamber?

- length of the detector can be reduced (to match the shadow of the magnet)?

- converge on the scale of the detector
