Detection of Six Pulsars at 2.8 cm

THE MPIfR 100 m radio telescope1,2 was designed to operate down to low centimetre wavelengths. Since May 1972 first tests, then astronomical observations at 11 cm wavelength have been made. One of the important test measurements was the investigation of the telescope's performance at all zenith angles. The tests confirmed the homologous behaviour of the telescope. More recently a 2.8 cm wavelength receiver was put into service. Again, tests show that the homology design does indeed work successfully at this short wavelength. The first tests exceeded the most optimistic hopes for the telescope's performance and a beam was achieved which indicates full usage of the 100 m surface area at this wavelength. As a result it was decided to make astronomical measurements where the large surface collecting area is used to the best advantage. The measurement of pulsars reported here is the first result of the 100 m telescope at 2.8 cm wavelength.
