[Solid_ec] EIC R&D proposal on EMCal

[Xiaochao Zheng]

Hi Alexandre:

The print time depends on the resolution (in all 3 directions). Wouter and Nilanga both told me it takes hours to print a sample that we designed for the shashlyk. We can't be very flexible in the transverse resolution due to fiber alignment, but we can relax the resolution in z. Wouter mentioned the z resolution (layer thickness) he is using is 1 micron. If 100 micron is good enough it might take only minutes (or tens of minutes) to print a sample. It is not out of the question to print all 1800 modules' layer if we buy 10 machines and run them 24/7 for 3 years.

How fast do you expect the printing process to be ?

(modified) first draft. The main idea is to test the quality of 3D-printed
scintillators. And if it works then eventually I'd like to see if we can
print scintillators for EM shashlyk-type calorimeter construction. If the
results from the first year look promising then I will request for funds
for prototyping in the second year.

calorimeter and one on tracking. For example Nilanga has been a major
player in the tracking consortium for a couple of years.

only focusing on the 3D-printed scintillators, as mentioned above. The
topic may look narrow but I feel this is a new technology and can fit well
into the EIC R&D.
