Data System; Computer Hardware - Thermo Scientific TSQ Series Hardware Manual

• RF voltage detector
• Mass DAC
• Integrating amplifier
The ion detection system electronic assemblies provide high voltage to the electron multiplier and
conversion dynode of the ion detection system. They also receive the electron multiplier output
current signal, convert it to a voltage (by the electrometer circuit), and pass it to the embedded
computer.
The ion detection system electronic assemblies include the following:
• Electron multiplier power supply
• Conversion dynode power supply
• Electrometer PCB
• Acquisition DSP
The Analyzer Control PCB contains circuitry for controlling and monitoring the operation of the
ion source, ion optics, mass analyzer, and ion detection system. These circuits are in turn
monitored by the PowerPC processor of the System Control PCB via the SPI bus.
The Analyzer Control PCB controls and monitors the rf voltages for Q0, Q1, Q2, and Q3
quadrupoles. It also has lens voltage drivers that convert ±330 V dc power from the DC Rod
Driver PCB to dc voltages that are applied to the lenses.

Data System

The data system controls and monitors the TSQ mass spectrometer. The data system also processes
data that the TSQ mass spectrometer acquires. The data system is composed of the following:
•

Computer Hardware

• Data System / Local Area Network Interface
Computer Hardware
The data system computer has the following major features:
• Intel
• High capacity hard disk drive
• Recordable/rewriteable CD drive
• Primary Ethernet port (data system to mass spectrometer)
• Secondary Ethernet port (data system to local area network)
• High performance video graphics card
• DVD drive
