TMO Standard Configuration

X-ray Parameters

The OPCPA laser system offers short (< 25 fs) 800 nm laser pulses. Harmonics of these pulses can be generated (400/266 nm).

MBES: Magnetic Bottle Electron Time-of-Flight Spectrometer in IP1

For Run 24 TMO will provide a magnetic bottle electron spectrometer. The spectrometer is coupled to a dual anode micro-channel plate detector allowing for some radial-discrimination of the measured spectrum.
The end station features:

• Gas targets:
  • Either heated gas needle or
  • In-vacuum oven
• 2m flight tube with retardation section, >50% collection efficiency
  • ​Resolution DE/E <5%
  • Retardation up to 200 eV
• Ion extraction plate and coincident Ion ToF capability
• Electron Detector
  • The spectrometer is coupled to a dual anode micro-channel plate detector allowing for some radial-discrimination 
  • In Run 22 we will test a prototype time-resolving camera (TIXEL) for electron detection. We will try to make this detector available for Users in Run 23, but this detector will be offered at risk.

MRCO: Angle-resolving Electron Time-of-Flight Detector in IP1

In Run 24 TMO will provide and angular array of electron time-of-flight spectrometers offering high energy- and angular-resolution for electron spectroscopy. This end station features:

• Gas targets:
  • Heated gas needle
• 16 eToF spectrometers, ~1% total collection efficiency
  • Resolution DE/E < 1%
  • Retardation up to 2000 eV
  • Angular Acceptance 1.5^o - 3.0^o cone angle, per ToF

Photon Spectrometer Diagnostic

In Run 24 we will offer a photon spectral diagnostic downstream of IP1. This device uses an off-axis Fresnel Zone-Plate (FZP) to spectrally disperse the incident X-ray onto a high repetition rate detector. A line-scan camera at maximum repetition rate of ~100 kHz will be used to measure the single-shot spectra at the absorption edges of carbon, nitrogen, oxygen and neon elements. This compact photon spectrometer has a designed resolving power of ~1000 which we have demonstrated at the oxygen K-edge.

X-ray Parameters

The Yb-based laser system will offer short (< 35 fs) 1030 nm laser pulses. Harmonics of these pulses can be generated (515/343/258 nm).

DREAM: Dynamic REAction Microscope at IP2

During Run 24 we will commission a reaction microscope spectrometer at the second interaction point in TMO. The standard configuration for Run 24 features ion detection with a 120 mm Hexanode delay-line detector. Electron detection is not part of the standard configuration and will be offered (at-risk). This end station features:

• Gas Targets:
  • Skimmed molecular beam source
• Charged Particle Detection:
  • 5 cm, short arm spectrometer (electron/ high-energy ions)
  • 27 cm, long arm spectrometer (lower energy ions)
  • Dual 120 mm Hexanode delay-line detectors.
  • Standard Configuration: Ions-only, either with long or short spectrometer.
