| Abstract: | Indus accelerator complex
houses two synchrotron radiation sources, Indus-1 and Indus-2. Electron beam
from booster synchrotron is injected into Indus-2 through transfer line-3
(TL-3). In order to reduce the radiation coming from TL-3 through the door
opening to Indus-1, to safe limit, a sliding shielding door has been developed.
It is a close welded frame of mild steel with required thickness of shielding
material in the form of interlocking lead bricks stacked inside. The door is
suspended from an overhead I-beam attached to welded wall brackets, which are
fixed to RCC wall using anchor fasteners. Pneumatic drive is used for moving
the door. Radiation measurements carried out after the installation show
substantial reduction in the radiation field at Indus-1 experimental hall.
Another safety concern is the inadvertent transmission of electron beam from
booster synchrotron to TL-3. For this purpose a safety shutter has been made.
It comprises of a beam absorber made of high density alloy DENSIMET which can
be moved in and out of electron beam path. Design, fabrication, installation
and testing of sliding shielding door and the beam shutter have been described. |
