Characteristics of the pocket:

Material	Length*Height [mm]	Thickness [µm]	Remark
Iron (Fe)	100*100	50	Window
Iron (Fe)	100*100	50	Window

Effective thickness measured with beam (170Er 1080 MeV /u): 120 µm Fe.

Update Nov. 05 2024: Presently installed wedge in the pocket is a wedge labeled "TS3DD2 (2)"

• TS3DD2 (2):

Size dX x dY = 120 mm x 118 mm, material AlMg3, density = 2.67 g/cm³.
Thin side 6.550 mm, thick side = 23.449 mm, slope = 0.14083 .
Central thickness = 4005 mg/cm².
Measured deviation from plane over full area: σ_z = 2.37 µm (0.633 mg/cm²).

This wedge was previously used for S475 experiment in 2020.

 

Other existing wedge, but presently not installed:

• Double wedge:
