斯派曼的 FIB 系列是专为聚焦离子束应用而设计的集成多输出高压电源。它结合了具有浮动输出的高稳定性加速器电压,以驱动传统的 Ga 离子和等离子源。

提供额外的透镜架,提供聚焦离子束所需的高性能固定或可逆极性高压透镜。主机箱和镜头机箱都可安装在 19 英寸机架上。聚焦离子束通常用于半导体工业、材料科学,并且越来越多地用于生物领域的材料成像、蚀刻和沉积。

主机箱提供高达 35kV 的加速电压,具有浮动灯丝、提取器和抑制器输出,所有这些都旨在满足 FIB 应用的严格性能要求。镜头底盘提供高达 30kV 的镜头电压,具有固定或可逆极性。


这种集成 FIB 电源系统的客户控制是通过光纤接口完成的。所有高压安全联锁均采用基于故障安全硬件的设计。

Input Voltage:

+24Vdc, ±5% @ 5.5 amps maximum. Inrush is <6 amps for 1 second.


Operating Temperature:

+10°C to +45°C ambient for normal operation. The unit will operate from 0°C but will require an extended warm up period.

Storage Temperature:

-20°C to +60°C


0 to 80% RH, non-condensing


2000 meters ASL at full power. For altitudes above 2000 meters the maximum ambient operating temperature is linearly derated by 1.1˚C per 300 meter interval.

FIB Input Power Connector:

2 pin Mate-n-Lok (TE 1-350942-0) 

FIB Communication:

Fiber Optics dual channel Avago HFBR- 2524z/1524z. RS-232. Ethernet RJ-45 socket which supports 100BaseTX. When Ethernet port is connected, RS-232 will not work. A Spellman Fiber Optic to RS-232 converter can be ordered, as well as a complete Fiber Optic to USB communication kit.

FIB Vacuum Interlock Connector:

Dual channel Avago HFBR- 2524z (receiver) /1524z (transmitter)

FIB to Lens Modules Interconnection:

The modules are supplied with interconnecting cables for the power and communications. The same kit is used to connect the FIBC to the lens module, and, if required, between a lens module and the next.

FIB HV Output Connector:

The main high voltage output is fitted with a custom 4 pole receptacle. A Spellman HV cable assembly, available in different lengths, can be ordered with the unit.

Lenses HV Output Connectors:

The lenses are fitted with Lemo ERA3Y430CTL receptacles. A Spellman 5 meters mating HV cable assembly can be ordered with the units. (See the product manual for additional cables and connectors information)

Safety Interlocks:

The vacuum interlock is an optical interlock. When it opens, the power supply is deactivated via relay contacts and will not reactivate until it is enabled through the computer control, even though the interlock may close. The FIB communication remains operational.

The interlock plate is situated around the FIB HV Output connector, and if removed will also disable all outputs.

The individual modules of the HVPS can be enabled and disabled through computer control, provided the appropriate hardware interlocks are enabled.

Note 1:
This is the time taken for the output signal of a module to settle (to 0.2% of the step size, or 1 V (20 mA for the filament), whichever is greater) in response to a ±2% or less (of full scale) step in its output, as measured from when the output first starts to change.

Note 3:
The above specifications do not apply in the range -500V to +500V
