HRC-I Out-of-Band QE and Effective Area
A model of the HRC-I MCP EUV - Visible quantum efficiency. A table of values for the model is provided.
HRC-I UVIS transmission in the EUV - Visible band. The model is based on a witness sample (TF100-1174) measurement (4400-8000 A) and linear attenuation coefficients from the literature. The boxes are two measurements at 1470 and 2537 A.

A model of the HRC-I EUV - Visible quantum efficiency. The boxes are two measurements at 1470 and 1850 A and an upper limit at 4400 A
A table of values for the model is provided.
A model of the HRC-I EUV - Visible Effective Area. A HRMA collecting area of 1100 cm2 has been assumed (constant over the band).
A table of values for the model is provided.

Quantum Efficiency vs Angle of Incidence
The relative quantum efficiency of a set of MCPs similar to the FM HRC-I MCPs was measured as a function of incident angle for the energy 1.49 keV at two azimuth angles. We will extend these measurements in our laboratory to more energies and azimuth angles.
The following diagram defines the angles theta (incident angle) and phi (azimuth angle) for the measurements:
A SPIE paper gives details of the measurement procedures, analysis techniques, and results of the XRCF and flat field calibrations.
