Altogether 16  tubes are mounted for the parasitic detector test (see the attached photos):

- two tubes (belonging to RIKEN) are in a 10 cm x 10 cm x 30 cm polyethylene matrix inside Eurica, the distance from AIDA is about 30 cm

- 12 tubes (belonging to RIKEN) are in a 20 xm x 30 xm x 30 cm matrix, outside (below) Eurica, at the closest possible place to AIDA, the distance is about 60 cm

- further two tubes (ORNL) are at the bottom of the Eurica support, about 1.2 m from the AIDA Silicon.

Furthermore, spectra measured using a 252Cf source is attached to this report, too (Jap1Cf-RIKEN tube, Us1Cf-ORNL tube). At the moment a background measurement is running.
