da08475b | 50 | Preface: all geometrical information (like left-right sides) is reported as seen from electronic side. |
d3da6dc4 | 51 | |
da08475b | 52 | |
53 | The DDL file starts with common header which size and structure is standartized and mandatory for all detectors. | |
d3da6dc4 | 54 | 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. |
55 | For HMPID the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13. | |
56 | ||
57 | Common header might be followed by the private one although HMPID has no any private header, just uses the common one. | |
58 | ||
da08475b | 59 | Single HMPID D-RORC (with 2 channels) serves a single chamber so that channel 0 serves left half (PCs 0-2-4) |
60 | 1 serves right half(PCs 1-3-5) | |
d3da6dc4 | 61 | |
62 | So the LDC -chamber-ddl map is: | |
da08475b | 63 | DDL index 0 -> ch 0 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601 |
64 | DDL index 2 -> ch 1 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603 | |
65 | DDL index 4 -> ch 2 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605 | |
66 | DDL index 6 -> ch 3 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607 | |
67 | DDL index 8 -> ch 4 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609 | |
68 | DDL index 10 -> ch 5 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b | |
69 | DDL index 12 -> ch 6 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d | |

71 | HMPID FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows. | |
da08475b | 72 | Each DILOGIC chip serves 48 channels for the 8x6 pads Channels counted from 0 to 47. |
d3da6dc4 | 73 | |
74 | The mapping inside DILOGIC chip has the following structure (see from electronics side): | |

d3da6dc4 | 76 | |
da08475b | 77 | 5 04 10 16 22 28 34 40 46 due to repetition in column structure we may introduce per column map: |
78 | 4 02 08 14 20 26 32 38 44 pady= 0 1 2 3 4 5 | |
79 | 3 00 06 12 18 24 30 36 42 addr= 5 3 1 0 2 4 | |
80 | 2 01 07 13 19 25 31 37 43 or vice versa | |
81 | 1 03 09 15 21 27 33 39 45 addr= 0 1 2 3 4 5 | |
82 | 0 05 11 17 23 29 35 41 47 pady= 3 2 4 1 5 0 | |

86 | 10 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure. | |
87 | DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10. | |
88 | 24 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes. | |
89 | 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 | |
90 | and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number. | |
