Geometry Description (CLAS12 NOTE 2016-?)
Detector Simulation Notes NOTE 2016-?)
Figure 1: View of the FTOF counters for CLAS12 highlighting the location of the panel-1 and panel-2 counters. The panel-1b counter arrays are shown in orange and the panel-2 counter arrays, mounted around the perimeter of the Forward Carriage, are shown in red. The panel-1a counter arrays mounted just downstream of the panel-1b arrays are not visible in this picture. The Forward Carriage is roughly 10 m in diameter.

Figure 2: View of the FTOF scintillators for panel-1a, panel-1b, and panel-2 in the sector mid-plane with the key parameters indicated.

Sectors
Figure 3: View of the upstream face of the Forward Carriage in Hall B showing the CLAS12 sector naming conversion for Sector 1 (S1) through Sector 6 (S6). The dashed lines denote the mid-planes for each sector.

Figure 4: View of the face of a generic FTOF panel-1a array showing the numbering scheme for the 23 scintillators that make up the counters in each of the six sectors of CLAS12.
Panel 1B
Figure 5: View of the face of a generic FTOF panel-1b array showing the numbering scheme for the 62 scintillators that make up the counters in each of the six sectors of CLAS12.
