57 Preface: all geometrical information (like left-right sides) is reported as seen from electronic side.
60 The DDL file starts with common header which size and structure is standartized and mandatory for all detectors.
61 The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index.
62 For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
64 Common header might be followed by the private one although HMPID has no any private header, just uses the common one.
66 Single HMPID D-RORC (with 2 channels) serves a single chamber so that channel 0 serves left half (PCs 0-2-4)
67 1 serves right half(PCs 1-3-5)
69 So the LDC -chamber-ddl map is:
70 DDL index 0 -> ch 0 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
71 DDL index 2 -> ch 1 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
72 DDL index 4 -> ch 2 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
73 DDL index 6 -> ch 3 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
74 DDL index 8 -> ch 4 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
75 DDL index 10 -> ch 5 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
76 DDL index 12 -> ch 6 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d
78 HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
79 Each DILOGIC chip serves 48 channels for the 8x6 pads Channels counted from 0 to 47.
81 The mapping inside DILOGIC chip has the following structure (see from electronics side):
84 5 04 10 16 22 28 34 40 46 due to repetition in column structure we may introduce per column map:
85 4 02 08 14 20 26 32 38 44 pady= 0 1 2 3 4 5
86 3 00 06 12 18 24 30 36 42 addr= 5 3 1 0 2 4
87 2 01 07 13 19 25 31 37 43 or vice versa
88 1 03 09 15 21 27 33 39 45 addr= 0 1 2 3 4 5
89 0 05 11 17 23 29 35 41 47 pady= 3 2 4 1 5 0
93 10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
94 DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
95 24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
96 Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number
97 and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.
99 HMPID raw word is 32 bits with the structure:
100 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
101 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095)
