This is a new twin anode X-Ray source specially designed by PSP
Vacuum Technology for the surface science research market. The TX400 can be
fitted with a variety of anode materials. It is easily adapted to most UHV
systems and can be supplied with direct or differential pumping |

| Power
Supply |
| The power supply provides the high voltage and
filament control to operate the source at power levels up to 500 W. The
filaments can be run in either the stabilized current or stabilized emission
mode. Safety interlocks are provided to shut off the unit in the event of a
water cooling failure |
| Voltage Regulation |
< 0.005% for specified line variations |
| Ripple |
< 0.02% of rated voltage at 0.5% rms |
| Stability |
0.01% /hr after 30 min warm up. 0.05% /
8hrs |

| Mechanical Details of the TX400 X-Ray Source |
| The source has twin anodes with independent filaments to provide
two separate excitation energies. Any combination of anodes can be chosen from
Mg, Al, Ti, Ag, and Zr. The anodes are replaceable so spare anodes can be
provides with different anode materials. The exit aperture has an aluminum foil
window to reduce Bremsstrahlung radiation and to isolate the anode for
differential pumping. The anode is water cooled. |
