TPC : standard
SVT : 3 layers
EMC : half barrel
ECAL: one third of one cap, west cap
TOF: two trays, TOFp & TOFr, on the east side; TOFp tray in East Barrel at the position 32, covers about 1 unit of pseudo rapidity and ~1/60th of the azimuth; TOFr tray in East Barrel at the position 23, the first full-scale MRPC prototype, covers in total ~30-40% of a unit of pseudo rapidity and ~1/60th of the azimuth;
pVPD: at the Z positions -564.4388 (East volume) and +563.4069 (West volume), radiator is quartz;
PMD: Photon Multiplicity Detector consists of two sensitive planes of hexagonal gas detector cellsi, one layer represents Charge Particle Veto (CPV) plane and other Pre-shower plane. Cells are arranged in 12 super modules consisting of varying number of Unit modules each of 24 x 24 cells. Layers of Lead and support Iron plate is sandwiched between two sensitive layers. PMD front face is placed at a distance of 539cm from center of TPC.

EMC : 3/4 of full barrel
ECAL: west cap
TOF: two trays, TOFp (at new location) & TOFr', on the east side;
TOFp tray in East Barrel at the position 33, covers about 1 unit of pseudo rapidity and ~1/60th of the azimuth;
TOFr' tray in East Barrel at the position 23, new construction, the 2nd generation prototype, covers in total ~30-40% of a unit of pseudo rapidity and ~1/60th of the azimuth;
pVPD: at the Z positions -574.5688 (East volume) and +573.5669 (West volume), radiator changed from quartz to plastic;
SSD: Silicon Strip detector contains two groups of 5 ladders ( 10 ladders in total), which centered at 6 and 12 o'clock if looking at the cross section of the detector. The tilts and angles of ladders are year-specific and described in sisdgeo.g
PMD: Photon Multiplicity Detector consists of two sensitive planes of hexagonal gas detector cell si, one layer represents Charge Particle Veto (CPV) plane and other pre-shower plane. Cells are arranged in 12 super-modules consisting of varying number of Unit modules each of 24 x 24 cells. Layers of Lead and support Iron plate is sandwiched between two sensitive layers.
