 Shielding Elements to MB-500 Mössbauer Bench

 


The MB-500 Mössbauer Bench has a basic shielding even if it is ordered without any shieding options. The parts with shielding are blue in this figure.

The Mössbauer source is located inside a cylinder consisting of layers of the metals aluminium, brass and lead. This sandwich design reduces the scattered radiation compared with a shielding by lead only. The thickness of the lead layer is 8 mm. The source shielding is available in two versions, the standard version and a version for quick sample exchange (Option MB-AH-02 see menu point 'Mechanical Setup').

Besides the shield around the source there is an additional shield round the proportional counter.
The lead has a thickness of 2,5 mm. A versions with enhanced shielding having an 8 mm lead layer is available: MB - DS - AP option

Set of  the shielding elements MB-ADPC-01 and MB-PCBS-01
The  shielding elements MB-ADPC-01 and MB-PCBS-01 can be used separately, each mounted on a slider, or as one unit consisting of both shielding elements, connected with a spring and without sliders. The right figure shows this unit, mounted on the detector holder.

MB-ADPC-01

Shielding adapter for proportional counter. Sandwich construction, mounted on a slider or attached to the detector holder together with the backside shielding may means of a clamp.

Backside shielding for the holder of the proportional counter.
This shielding element  provides 24 mm more lead shielding in axial direction in addition to the integral shielding of the holder.
