Add a missing tilt in Neutron Shielding

Add a missing tilt in Neutron Shielding

@gcorti @adavis @kreps

The description of Neutron Shielding is currently missing a tilt of -0.206 degrees with respect to the LHC accelerator coordinate system.

Panoramix

1. Running panoramix

lb-run --nightly lhcb-head/2950 --platform=x86_64-centos7-gcc9+py3-opt Panoramix/HEAD python ns_tilt_script.py

2. Panormaix setup

from LHCbConfig import *
from PanoramixSys.Configuration import *

importOptions('$PANORAMIXROOT/options/PanoramixVis.py')

lhcbApp.DataType   = 'Upgrade'
lhcbApp.Simulation = True
lhcbApp.DDDBtag    = "upgrade/mimazure-ns-tilt"
lhcbApp.CondDBtag  = "upgrade/master"

import GaudiPython as GP
import gaudigadgets

appMgr = GP.AppMgr()
appMgr.initialize()

from panoramixmodule import *
toui()

I drew violet lines that are perpendicular to the LHCb coordinate system for reference.

Before (upgrade/master)

After (upgrade/mimazure-ns-tilt)
