3 RheinischWe stfaelische Ho chschule Aa chen Gas Manifold v. 00 Assembly of Pressure Transducers on Gas Manifold v. On each gas manifold of the CMS DT chambers one 00 mbar and one 00 mbar pressure transducer as well as the preamplifier PCB are mounted. pressureinlet HR 0004 Fig. : Pin of the sensor is marked by a small notch. The pressure inlet, to be glued to the manifold, is opposite to pin 4. The sensors are of type Motorola MPX00DP (00 mbar) and MPX00DP (00 mbar, shown here). 00 glue pin Fig. : Assembled manifold, with top cover removed. Looking from outside, the cables connecting the sensors to the preamplifiers are located: left, with pin at top, for the 00 mbar sensor, and right, with pin at the bottom, for the 00 mbar sensor. 00 pin File: 00anl_verteiler_v.eps 00 pin HR 00 HR 00 Fig. : In this view pin of both sensors is at the BOT TOM, the 00 mbar sensor is the REAR one and the glued inlets are at the TOP. 00 glue page manifold_0 File: 040DTGasManif.pdf

4 Rheinisch Front: Definitions L N tl N tp this is the FRONT face L Fig.: Front manifold and support pieces. The plate size is 00mm x mm x mm, while the Lprofile (top) and the bar (bottom) are mm long. The many holes, with a pitch of mm, permit to adapt the support to every chamber type. N bp N bb Fig.: Front manifold support for a "left" chamber. The variables indicated count the first hole used at the top Lprofile (Ntl), the top of the plate (Ntp), the bottom of the plate (Nbp) and the bottom bar (Nbb). (These values are here Ntl =, Ntp =, Nbp = and.) Counting is always from the side with the fittings. 00 BP/hr Lpp N tp N tl L t 4. L L 00 BP/hr 00 BP/hr N L N bb b bp Fig.: Front manifold support for a "right" chamber. Counting is from the side with the fittings, thus here from the right (the values are thus here Ntl = 4, Ntp =, Nbp = and ). Similarly, the length (in mm) from the outer face of the next corner block of the SuperLayer to the first screw of the supporting profiles into the SL frame, Lt and Lb, are also indicated. The length L, L,, Lpp is the length to which the flexible tube is to be cut. The length serving to connect to the patch panel on the iron, Lpp, is still to be checked and will only be needed once the chamber is inserted into the CMS yoke. Fig.4: Front manifold support for a "left" chamber; lateral view. Minicrate, cabling, carter, etc. are not shown. Notes on MB4 chambers: The s of MB4 chambers do not need the support above but can be attached directly to the Cprofile of the honeycomb panel, much like the s, but the front ones do not need a spacer plate. For MB4 chambers the relevant geometry here is related to its position at the "left hemisphere" ("sx") or at the "right hemisphere" ("dx") rather than being on a "+Z" or on a "Z" wheel. In the special case of MB4/4 and MB4/0 there are two chambers in the same slot ( twin chambers) and thus an s and d are added to specify the left and right twin chamber, respectively (as usual, when seen from the interaction point). page manifold_0 File: 00DTGasManif.pdf

Gas manifold and PADCbox are attached to the Cprofile through spacer plates to ensure free access to the outer two threaded holes at left and right, for handling of the chamber. On all MB4 chambers (have no SLtheta and honeycomb panel is accordingly thicker) the fixation holes are ~ mm higher but this also holds for the alignment passages. Therefore the same gas components also fit on MB4; keep the lateral gas pipe at the upper border of its passage. 00 BP/hr gas manifold cut AA HV side, layer phi X PADC.
