H2GCROC-based AHCAL could be cost-effective compared to RADIOROC-based solution (see Yasu's slide).
For the first prototype of H2GCROC based AHCAL, equivalent to 1 layer (18 x 18 = 324 ch, same as CEPC AHCAL), 25 kCHF could be a good guess.
- wrapped 4 cm x 4 cm scintillator (1-2 kCHF, 3 CHF per 1 ch in case for 13000 ch; will be asked to IHEP by Zhen?),
- backplane of scintillator without ASIC (for 1 layer; like 3 units of HBU; will be asked to USTC by Zhen?)
- SiPM (x 324 plus spares, 4 kCHF depending on what CMS HGCAL uses; will be asked to CMS by Zhen?)
- LED (x 324 plus spares, TBC, will be asked to USTC by Zhen?)
- Front End Board with H2GCROC (2 boards, each of them has 3 x H2GCROC, a few kCHF; will be confirmed with EIC people by Yasu?)
- Cables (<1 kCHF)
- Felix (8 kCHF)
