Rock West Composites Delivers to Purdue University the Barrel Timing Layer Tracker Support Tube for CERN's Large Hadron Collider
Published : May 15, 2026
Rock West Composites (RWC) apprised of the delivery of the Barrel Timing Layer (BTL) Tracker Support Tube to Purdue University this month. This large carbon fiber sandwich structure destined for CERN was designed by a joint team from Purdue University, led by Dr. Andy Jung and Dr. Ben Denos, and RWC, led by John Marks. The delivered hardware is 5.3-meters long by 2.4-meters in diameter. It is constructed of ultra-high-modulus prepreg and Nomex honeycomb core made with PMT-F6 cyanate ester resin. There are 1680 metallic inserts made of solid carbon epoxy, titanium and stainless steel; and it includes two 110 MSI carbon fiber (K13916/ F6) rails to support scientific instruments. Surface accuracy requirements were tested to 2.4mm cylindricity inhouse before shipment.
CERN is the world's leading laboratory for particle physics located near Geneva, Switzerland. The carbon fiber tube supports the heart of the upgraded CMS detector, a "camera" with more than a billion pixels to record proton-proton collisions at the highest ever-made energies and unprecedented resolution.
