Test of a full scale sector for a 1 m long high resolution vertex chamber
We have tested a 1 m long prototype sector consisting of 170 rectangular drift cells. The sector is arranged in 25 radial layers, of which the 13 inner layers have cell sizes of 10 mm x 15 mm and the 12 outer layers of 14 mm x 21 mm. To measure the coordinates of a track along the wire, 13 axial lay...

The sector is arranged in 25 radial layers, of which the 13 inner layers have cell sizes of 10 mm x 15 mm and the 12 outer layers of 14 mm x 21 mm. To measure the coordinates of a track along the wire, 13 axial layers are interleaved with 12 stereo layers. Special care was taken to keep cell sizes as homogeneous as possible to obtain the same space vs drift-time relation for all layers of the same cell size.A low diffusion gas mixture of 85% CO"2 plus 15% isobutane was used in a closed loop gas system, including a purifier, run at an absolute pressure of 1 and 2 bar and stabilized within a few mbars by a microprocessor system.The chamber signals were read-out with TDCs. In the central part of the drift length we achieved space resolutions of 35 μm per cell at atmospheric pressure and 25 μm per cell at 2 bar pressure. These figures correspond to axial resolutions of 0.5 to 1 mm per stereo layer. | ||

Test of a full scale sector for a 1 m long high resolution vertex chamber |
| abstract |
We have tested a 1 m long prototype sector consisting of 170 rectangular drift cells. The sector is arranged in 25 radial layers, of which the 13 inner layers have cell sizes of 10 mm x 15 mm and the 12 outer layers of 14 mm x 21 mm. To measure the coordinates of a track along the wire, 13 axial layers are interleaved with 12 stereo layers. Special care was taken to keep cell sizes as homogeneous as possible to obtain the same space vs drift-time relation for all layers of the same cell size.A low diffusion gas mixture of 85% CO"2 plus 15% isobutane was used in a closed loop gas system, including a purifier, run at an absolute pressure of 1 and 2 bar and stabilized within a few mbars by a microprocessor system.The chamber signals were read-out with TDCs. In the central part of the drift length we achieved space resolutions of 35 μm per cell at atmospheric pressure and 25 μm per cell at 2 bar pressure. These figures correspond to axial resolutions of 0.5 to 1 mm per stereo layer. |

The sector is arranged in 25 radial layers, of which the 13 inner layers have cell sizes of 10 mm x 15 mm and the 12 outer layers of 14 mm x 21 mm. To measure the coordinates of a track along the wire, 13 axial layers are interleaved with 12 stereo layers. Special care was taken to keep cell sizes as homogeneous as possible to obtain the same space vs drift-time relation for all layers of the same cell size.A low diffusion gas mixture of 85% CO"2 plus 15% isobutane was used in a closed loop gas system, including a purifier, run at an absolute pressure of 1 and 2 bar and stabilized within a few mbars by a microprocessor system.The chamber signals were read-out with TDCs. In the central part of the drift length we achieved space resolutions of 35 μm per cell at atmospheric pressure and 25 μm per cell at 2 bar pressure. These figures correspond to axial resolutions of 0.5 to 1 mm per stereo layer.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Deutschmann, M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hawelka, P.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Herten, U.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tonutti, M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Nuclear Instruments and Methods in Physics Research Section A:</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">252(1986), 2-3, Seite 379-383</subfield><subfield code="w">(DE-627)NLEJ180854372</subfield><subfield code="w">(DE-600)1466532-3</subfield><subfield code="x">0168-9002</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:252</subfield><subfield code="g">year:1986</subfield><subfield code="g">number:2-3</subfield><subfield code="g">pages:379-383</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0168-9002(86)91208-8</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">252</subfield><subfield code="j">1986</subfield><subfield code="e">2-3</subfield><subfield code="h">379-383</subfield></datafield></record></collection>
