Side view of the TPC showing clearly the 30 x 33 MegOhm resistor
divider chain. On the L.H.S. we see the HV input and cable for the
TPC. On the R.H.S. the GEM voltage protection resistors are on the
motherboard and they are covered with silicone. |

Side view of the TPC showing a clear view of the TPC HV input. |
|
Side view of the TPC on the side of the GEM HV inputs. The resistors
are for breakdown protection. The GEM HV divider chain is external and it
is not shown. |

Side view of TPC next to an aerosol can (for scaling). |

TPC and GEM assembly is positioned inside the hermetic vessel. The
detector is upright on 3 posts. An opened window port is shown. |
|
The TPC+vessel assembly seen from the top. The top TPC electrode is
solid. The last component is an insulating ring for support of the TPC
structure when it is positioned on its side. The TPC HV line is soldered
at the centre of the last electrode.

View of the "business end" of the detector (HV and signal
input/outputs). The detector is mounted side ways on its support
brackets. The TPC 10 keV HV connector is on the L.H.S. while the GEM
mutipin HV input connector is on the R.H.S. |

View of the top lid. NEVER stand the detector on that face. |

From the top, 2nd mylar window. The two remaining window ports are are
sealed with solid flanges. |
