4.B3 ISAC Drift-Tube Linac

Four of the five 106-MHz radiofrequency cavities making up the ISAC Drift-Tube Linac (linear accelerator), with its designer Bob Laxdal (right).

The DTL accelerates 150 keV/u ions from the RFQ Linac (in the red vacuum tank in the background) to 1.5 MeV/u for experiments in nuclear astrophysics.
