Table 1. Factors affecting the forward-scattering signal for phantoms #1 and #2.

Phantom number	Incident flux (photons s−1 meV−1)	Transmission of Si base on sample	57Fe layer transmission due to photoelectric absorption	Time-integrated delayed transmission after 57Fe layer	APD efficiency (absorption of Si piece in APD)	X-ray transmission in air (1.0 m from sample to APD)
#1 (APD rotated 80°)	6 × 107 (with pinhole)	0.28 (500 µm)	0.95 (1 µm)	7.62Γ0 (1 µm)	0.74 (580 µm)	0.82
#2 (sample rotated 55°)	1.5 × 109 (without pinhole)	0.11 (872 µm)	0.95 (1.1 µm)	8.59Γ0 (1.1 µm)	0.21 (100 µm)	0.82
