The delay cable used in the Pion Beta Detector was delivered by our Russian collaborators (S. Korenchenko et al). It's type is PK-50-2-16 and was produced in a factory in Siberia. It was cut to 75m (385ns delay) and bunched in groups of sixteen. The physical properties were measured at PSI and at UVa. The results compared with standard RG-58 cable are the following:
| Outer diameter | 3.5 mm | 5 mm |
| Impedance | 50 Ohm | 50 Ohm |
| Dielectric | Polyethylene | |
| Signal* propagation speed | 19.8 cm/ns | 19.6 cm/ns |
| Signal* rise time after 350ns delay | 8.3 ns | 8.2 ns |
| Signal* peak attenuation after 350ns delay | 0.535 | 0.575 |
| Attenuation at 50 MHz | 4.18 dB/100ft | 3.54 dB/100ft |
| Attenuation at 100 MHz | 7.55 db/100ft | 5.53 dB/100ft |
* Measured with a standard CsI pulse of 6ns rise time and ~30ns decay time
