A double coil system has been designed for measuring the magnetic field of a de-flection yoke. A general formula for calculating the field parameters of H0, H2 and H4 is derived when the measuring double coil is in any two positions on x (or y) axis. Even when there exists a small difference o f sensitivities between these two coils, the formula should stili be valid. Measurements are processed by the regression analysis along the x (or y) axis in order to obtain the optimum values for the field parameters....

The temperature dependence cf the pbotoiuminescer.ee in GaPiN has been investigated in the range of 20K-120K. The following experimental phenomena show that there would be exciton transfer between different luminescent centres in GaP:N.

The temperature dependence cf the pbotoiuminescer.ee in GaPiN has been investigated in the range of 20K-120K. The following experimental phenomena show that there would be exciton transfer between different luminescent centres in GaP:N. (1) With the increase cf temperature from 20K to 60K, the emission intensity of higher energy band (18760cm-1-18280cm-1) decreases rapidly, while that of lower energy band (17640cm-1 -17050cm-1) increases. However, the total intensity of all luminescent lines decreases slowly when the temperature increases from 20K to 60K, and decreases rapidly when T exceeds 60K. (2) As the temperature is raised from 20K to 60K, for the deeper binding centres (e.g. NN1,NN3) the emission intensity increases appreciably, (3) The NN1 line and its phonon sidebands have been observed under A line exciting. This selective excitation experiment shows that at 77K there is exciton transfer from the isolated N to the NN1 pair.In the range of 20-120K, the exciton transfer is mainly the transfer produced by re-distribution of excitons due to thermal ionization of shallower bound excitons. The exciton transfer proceeds on the sequence of A→NN6→NN5→NN4→NN3→NN1 with the increase of temperature.Using above band gap excitation, because of the exciton transfer there is error of the activation energy (E), which is acquired from fitting experimental data to the formulaTo be specific, for deeper binding centres, which receive excitons from other centres, the exciton transfer causes E to increase.Considering the influence of exciton transfer on the thermal quenching, A line and NN6 line are found to be thermal quenched by the escape of excitons, so their activation energy would be equal to the binding energy of exciton. However, for NN1, NN3 lines, the luminescence is quenched by the escape of hole, so their activation energy would be equal to the ionization energy of hole (i.e.40meV). For NN6, NN4 lines, because the fitting data of their activation energy clcse both to the binding energy of exciton and to the ionization energy of hole, it is difficult to judge their thermal quenching mechanism.
