CS-Pad
Cornell-SLAC Pixel Array Detector
CsPad geometry, as described in ElementIterator.hh
// Each "Element" represents one quadrant of a complete detector // and they are arranged as follows (viewed from upstream): // +---+---+ // | 0 | 1 | // +---+---+ // | 3 | 2 | // +---+---+ // // Each "Element" is composed of 8 "Section"s arranged as follows: // +---+---+-------+ // | | | 6 | // + 5 | 4 +-------+ // | | | 7 | // +---+---+---+---+ (for quadrant 0) // | 2 | | | // +-------+ 0 | 1 | // | 3 | | | // +-------+---+---+ // The layout of each successive quadrant is rotated 90 degrees clockwise // with respect to the previous quadrant. // // Each "Section" is composed of 2*194 rows by 185 columns with the following // orientations (for quadrant 0): // Sections 0,1: row index increases from bottom to top, column index increases from left to right // Sections 2,3: row index increases from left to right, column index increases from top to bottom // Sections 4,5: row index increases from top to bottom, column index increases from right to left // Sections 6,7: row index increases from left to right, column index increases from top to bottom // Again, the orientations of the Sections for quadrant 1 are rotated 90 degrees clockwise // and so on for each successive quadrant. //
Here's a picture showing the approximate position and alignment of the sections in the CSPAD detector image. The value of each pixel is set to increase with increasing row and column number, so the blue corners are (row 0,column 0) in the section array.
