Hi,
I committed the geometry in svn, and launched the check of overlaps for ONLY the new beam pipe.
This is what I obtained:

====================================================================
STAGE 1: Overlap checking by sampling within 10 microns
====================================================================
Info in <TGeoNodeMatrix::CheckOverlaps>: Checking overlaps for cave and daughters within 0.001
Info in <TGeoNodeMatrix::CheckOverlaps>: Checking overlaps by sampling <s> for cave and daughters
Info in <TGeoNodeMatrix::CheckOverlaps>: === NOTE: Extrusions NOT checked with sampling option ! ===
Info in <TGeoChecker::CheckOverlapsBySampling>: #Found 2 overlaps adding-up to 3049.03 +/- 280.686 [cm3] for daughters of BeamPipe
Check overlaps:      [==========]   11 [100.00 %]   TIME 00:00:54             
Info in <TGeoNodeMatrix::CheckOverlaps>: Number of illegal overlaps/extrusions : 2

====================================================================
STAGE 2: Global overlap/extrusion checking within 10 microns
====================================================================
Info in <TGeoNodeMatrix::CheckOverlaps>: Checking overlaps for cave and daughters within 0.001
Check overlaps:      [==========]   11 [100.00 %]   TIME 00:00:00             
Info in <TGeoNodeMatrix::CheckOverlaps>: Number of illegal overlaps/extrusions : 2

====================================================================
STAGE 3: Propagating 1000000 tracks starting from vertex
 and conting number of boundary crossings...
====================================================================
Transporting tracks  [==========] 1000000 [100.00 %]   TIME 00:00:06             
Time for crossing 2050289 boundaries: 6.08e+06 [ms]
Time per track for full geometry traversal: 6.08 [ms], per crossing: 2.96544 [ms]
====================================================================
STAGE 4: How much navigation time per volume per next+safety call
====================================================================
Time for volume cave (assemb=0): 0.67 [ms] ndaughters=1 ncross=1024810        
Time for volume BeamPipe (assemb=1): 0.82 [ms] ndaughters=9 ncross=1025479    
Time for volume gvhesr (shape=VATvalve100): 0.43 [ms] ndaughters=0 ncross=239 
Time for volume pipeup (shape=pipeup): 0.24 [ms] ndaughters=0 ncross=291      
Time for volume ktmpump (shape=ktmpump): 0.6 [ms] ndaughters=0 ncross=983     
Time for volume Tpump (shape=Tpumps): 1.46 [ms] ndaughters=0 ncross=2605      
Time for volume pipeTSup (shape=pipeTSup): 0.25 [ms] ndaughters=0 ncross=16487
Time for volume Tcross (shape=Tcross): 1.62 [ms] ndaughters=0 ncross=997875   
Time for volume pipeTSdown (shape=pipeTSdown): 0.25 [ms] ndaughters=0 ncross=2619
Time for volume crossTSTMPs (shape=crossTSTMPs): 2.57 [ms] ndaughters=0 ncross=4060
Time for volume DipolePip (shape=Dippip): 1.98 [ms] ndaughters=0 ncross=320   
STAGE 4 completed    [=========/]   11 [ 91.67 %]
root [9] gGeoManager.PrintOverlaps()
=== Overlaps for FAIRGeom ===
 = Overlap ov00000: BeamPipe/gvhesr_0 overlapping BeamPipe/pipeup_0 ovlp=0.0825
 = Overlap ov00001: BeamPipe/crossTSTMPs_0 overlapping BeamPipe/DipolePip_0 ovlp=0.005
root [10] 


Two internal overlaps are present, maybe some fixes are needed.
