[Eugene Pasyuk]

I have a couple of questions from Bob about the HyCal location: please respond ASAP.

Thanks Eugene,

As I develop the model, I will email you specific questions.

Once I get a model complete, then we can review it together to go over more details.

Next question:

For PRad 2, with the addition of the second GEM, the distance from the harp center to the upstream window of the hycal is 7.09 m.

For X17, the requested distance from the harp center to the upstream window of the hycal is 7.5 m.  To keep the 7.5 m, I will need to move hycal downstream another 0.41 m.  Is that the correct course of action?

Thanks,
Bob

Hi Eugene,

I am working on the GEM layout for PRad 2.

If the 40 cm spacing for the GEMS from foil to foil, or is there to be a 40 cm gap between the GEM frames?

Thanks,
Bob
