3D Drawing of the photon detector vessel and PMT holder
Version of 27/Sep/05

• Modification log
• Inner Vessel drawing and PMT holder drawings are updated. (27/Sep/2005)
• new drawing is added for the end flange of the inner vessel with screw holes to fix aluminum spacer blocks and patch panels. (19/Aug/2004 by SM)
• Inner vessel drawing was modified to include supporting holes on the end flanges. (23/Aug/2004 by SM)

Assembly of the inner vessel and PMT support (updated on 11/Jan/05. Version of 050106) [IGES][STEP] This version is valid only for Version of 050106 This version includes patch panels to be installed in the cryostat. Assembly file in Inventor format. Please download related parts and assembly files from folders, Inner vessel, PMT support and Patch panel.
Detailed drawing of the inner holder (uploaded on 26/Sep/05. Version of 050926) [IGES] [STEP] Inventor (ver. 8) format can be found in this folder.

For installing the support structure into the inner vesel, 4 kinds of parts must be welded on the inner side for the inner face support and one kind of L-shape part needs to be welded for the outer face support as shown in the assembly drawing. 3D drawings of each part are listed below. Please refer the above drawings for relative position to the vessel or to the 2D drawings included below.

For supporting the patch pannel and spacer aluminum blocks, we are considering making holes on the inner vessel flange, perpendicular to the cover fixing screw holes, as shown in the drawing on the right side. This modification is already included in the above drawings of "inner vessel" and "assembly of inner vessel and PMT support".

• Patch panel design
Inventor format files can be found here. Download seperate part files from this directroy. The assembly file name is "patchpanel.iam" and "patchpanel_MIR.iam"(mirror image of the first one).

• Things to be done
• Due to the shift of the inner face wall location from the previos 2D-drawing, we need to optimaize again the spacing of the inner face PMT slabs, resulting in modifitaion of all PMT support sturucture (althrough it is very slight). done on 23/Aug/2004
• Supporting hole/screws for the spacer aluminum blocks, done on 19/Aug/2004
• Aluminum spacer design
• Patch pannel design, uploaded 24/Nov/2004
• cabling design
• sensor (temperature and surface level meter location)
• calibration wire installation
• ionization chamber installation
