We have obtained evidence of gamma-ray emission above 1 TeV from PSR1706-44, using a ground-based telescope of the atmospheric Čerenkov imaging type located near Woomera, South Australia. This object, a γ-ray source discovered by the COS B satellite (2CG342-02), was identified with the radio pulsar through the discovery of a 102 ms pulsed signal with the EGRET instrument of the Compton Gamma Ray Observatory. The flux of the present observation above a threshold of 1 TeV is ∼ 1 · 10^-11 photons

The analysis is not restricted to a search for emission modulated with the 102 ms period, and the reported flux is for all γ-rays from PSR1706-44, pulsed and unpulsed. The energy output in the TeV region corresponds to about 10^-3 of the spin down energy loss rate of the neutron star.
