Capabilities:

• World’s leading DualBeam Helios 5 platform has automatic alignments to make sure that every user is able to acquire world class images for a variety of applications.
• 360 degree infinite rotation cryo stage allows for TEM sample prep with the cryo EasyLift (CLO) nanomanipulator along with making the Helios an analytical powerhouse. Heaters within the stage and CLO allow for temperature adjustment from room temperature down to approximately -190C.
• MultiChem GI deposition allows for up to 6 chemistries to be deposited and mixed in situ which makes the Helios a materials innovation engine. Presently with carbon, tungsten, and platinum.
• Highest-quality, site-specific, sample preparation for TEM and APT using new high throughput Tomahawk HT Ion Column
• Fastest and easiest, fully automated, unattended, multisite in situ and ex situ TEM sample preparation and cross sectioning using AutoTEM 5 Software
• Shortest time to nanoscale information for users with any experience level using best-in-class Elstar Electron Column featuring SmartAlign and FLASH technologies
• Most complete sample information with sharp, refined and charge-free contrast from up to six integrated in-column and below-the-lens detectors
• Highest-quality, multi-modal subsurface and 3D information with the most precise targeting of the region of interest using optional Auto Slice & View 4 (AS&V4) Software
• Fast, accurate and precise milling and deposition of complex structures with critical dimensions of less than 10nm

Software for Computational Analysis

Auto Slice and View 4.0 (AS & V4) software acquires high-resolution data by milling serial sections (slices) of a specimen with a focused ion beam and then imaging and/or mapping each slice generating large stack of images.

The stack of images and their parameters are seamlessly read from the data headers of the images with Amira and Avizo software package thus allowing the user to generate 3D electron density maps of the specimen.

Quick data transfer and fast computational image processing allows users to visualize their results while rest of data acquisition is still underway.

Automatic Artificial Intelligence software package Aivia offers the users for quick and easy segmentation results.
