Emittance Scanner, 1.5 kW
Complete Emittance & Phase Space Scanner System for beams up to 1.5 kW. Our most popular beam diagnostic.
ES-4
The D-Pace ES-4 Emittance and Phase-Space Scanner system measures low-energy charged particle beam distributions in (x, x’) or (y, y’) depending on installed orientation. Important physical parameters are computed and displayed such as RMS emittances, and the beam phase space intensity distribution. The system includes everything you need to conduct an emittance and phase-space scan, including the probe, controller (3U chassis), 15 meter cables, and software. The vacuum box is sold separately – see related products links below.
Our system now supports emittance scans on pulsed beams!
- Measure magnitude of emittance for low-energy charged particles (<1MeV)
- Water-cooled head for beam power up to 1500 W and 500 W/cm2
- Determine phase space ellipses by any percentage of total beam or RMS emittance
- Use data for modelling beam transport in ion-optical analysis software
- Molybdenum front face and slits for thermal performance and low sputtering
- Dual scanner configurations (x,y) available, with collision-prevention interlocks
- Pulsed and continuous wave (CW) emittance scanning capability
- EPICS Compatible
The D-Pace Emittance and Phase Space Scanner System is an Allison-type emittance scanner, combining an electric trajectory sweep technique with a mechanical position beam sweep, enabling the simultaneous measurement of position (y) and angle (y’). Two probes can be used to scan horizontal and vertical plane phase spaces, or a single head can be used by re-mounting the head on a port 90° to the first .
The software enables the operator to optimize scans for resolution and scan time, and to plot beam profiles, 2D and 3D contours with and without emittance ellipses. Data is saved as an CSV file. Use our Windows/Linux compatible user interface, or remotely operate the scanner via EPICS compatible TCP-IP text based commands.
The ES-4 Emittance Scanner is licensed from TRIUMF.
Want a demo? This scanner is installed on our own Ion Source Test Stands. We can provide an in-person or remote demonstration.
Need a custom insertion length? We can customize the probes with longer actuator shafts.
