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




		SLD-500 Shielding Disk for the backside of the velocity transducer. The disk has a sandwich shielding with an 8 mm thick lead layer.
		SLD-500A Enhanced shielding disk with up to 32 mm lead layer
		SLD-501 Shielding Disk for the frontside of the velocity transducer. The disk shields the backwards directed radiation. It has a hole for the source adapter withthe source. The lead layer of the sandwich shielding has a thickness of 8 mm.
.		MB-EXT-01 (length 50mm) MB-EXT-02 (length 80mm) Extension tube This tube is used if the distance between absorberand detector has to be increased. Its has a sandwich shielding with an 8 mm lead layer.
		MB-PCFBS-01 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.
		MB-PCBS-01 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.
