ATHENA_1sh_both InstrumentA model of the ATHENA-telescope using just a single shell as optical element. That means to make use of this instrument it is necessary to run a series of simulation while varying the input parameter shellnumber. The model needs as input a file geomfile, which contains (in ascii) tabled details about the geometry of the shells. The data in the geomfile is assumed to be in the format: #row L/m rad_h/m rad_m/m rad_p/m width/m ... row: running index for the rows/rings L: The length of the plates for this ring rad_h: The radius at the "hyperbolic" end of the optic. At the detector end. rad_m: The radius at the midpoint of the optic. This is the reference. rad_p: The radius at the "parabolic" and of the optic. At the source end. Example: ATHENA_1sh_both.instr shellnumber=1
| Name | Unit | Description | Default |
| FL | m | The focal length of the optical system | 12 |
| optics_dist | m | The distance between souce and optic. In space this would be quite large :-). | 10 |
| XWidth | m | The width of the user detector default is that of the ATHENA WFI large area detector | 0.13312 |
| YHeight | m | The height of the user detector default is that of the ATHENA WFI large area detector | 0.13312 |
| NX | Number of pixels along X in the user detector | 1024 | |
| NY | Number of pixels along Y in the user detector. | 1024 | |
| reflectivity | Data file containing reflectivities (such as from IMD) | "mirror_coating_unity.txt" | |
| E0 | keV | Central energy of X-rays | 5 |
| dE | keV | Half spread of energy spectrum to be emitted from source | 0.001 |
| shellnumber | The row number for the miror module. This defines the shell. | 1 | |
| geomfile | File which contains the geometry of the pores (i.e. radii,lengths) | "ATHENA_rings_1_20.dat" | |
