First version for MuonAGDD-00-00-06 from AMDB M2.8 |
The following documentation presents the elements and attributes used to describe specific detector components of the ATLAS Muon Spectrometer. The names are specific to the AGDD descriptions. However, as there is currently a one-to-one mapping between AGDD and AMDB, the documentation is useful for understanding the AMDB.
Element of type composition. Contains the complete description of the Endcap Toroids of the ATLAS Detector. It comprises 8 ENC_TOR elements multi-positioned in phi.
Element of type ENC_Toroid. One of 8 phi sectors of the endcap toroid.It is composed by one ENC_COND_BOX , a system of support plates ENC_SUPP_PLATES and an external envelope ENC_CRYO.

| Cond_Box_Desc | CONDUCTOR BOX | IDREF to ENC_COND_BOX |
Element of type ENC_Cryostat.It consists in an outern surface divided in two sectors,composed by the elements ENC_CRYO_Outer_surf , ENC_CRYO_Side and ENC_CRYO_Inner_tube,and a tube embedded in the middle (ENC_CRYO_STAYTUBE).
