General Specification and notes of HATA Holder system
Virtual pivot system(TM)
Back lighting system
High Angle Triple Axis Holder System (TEM holder)
Item Name: HATA-Holder System ( Set of HATA- Holder for ST with Index Dock System )
Item number: 911 0624 5001
▶ Applicable instrument: FEI Tecnai Super Twin series and Titan.
▶ Model name: HATA-8075-ST ( High Angle Triple Axis Holder )
▶ CFS ( Compartments to Fasten Specimen ) - Attachable cartridges
▶ Maximum Alpha tilt range +/-80 Degrees
(Limited by the max stage tilt, for gap such as Super Twin pole piece)
Note: Beam might be shadowed by specimen grid and CFS itself. Note:
▶ Maximum Alpha tilt might be limited by Gonio Stage condition.
▶ Maximum Beta tilt range +/- 7.00 Degrees.
(Fully Motorized control )
▶ Maximum Azimuth rotation range +/-5.00 degrees.
(Controlled by off-line Index Dock System )
Index Dock System
Model name: HATA-IDS005
Maximum rotation (azimuth) ranges +/-5.00 Degrees .
▶ Minimum step control of angle is 1/100 Degree by micrometer.
▶ The rotation angle is displayed with a digital meter.
brightness control there.
Index Dock System is bridge fame structure, therefore comfortable pass to the Binocular stand base.
▶ Bridge fame height clearance is adjustable by four independent stands.
New concept and latest technology
▶ Patent protected Beta axis tilt mechanism with a virtual Beta angle Pivot.
▶ Virtual pivot, our solution that grants advantage no other holder can offer.
▶ Allows crystal orientation compensation with Beta Tilt at High Alpha angles with a decided rotation.
▶ We utilize the limited pole piece gap in a way that has never been utilized before.
▶ The concept increases the efficiency of X-Ray detection.
CFS:"Compartments to Fasten Specimen" Attatchable catridge system
▶ CFS is a flexible cartridge system for various purposes.
▶ After setting the specimen rotation angle, simply fix the cartridge back on the holder.
▶ Allows easy transfer to other environment such as FIB chamber.
▶ With this solution a number of cartridges can be processed and re-processed inside FIB chamber without physically touching the sample itself.
▶ Possibility to have as many cartridges as you wish for only one HATA-Holder means
▶ you can store your precious sample inside a cartridge for years and the just fit it to the holder rod for another observation with the exact same orientation and position.
▶ We can also offer specially designed low background cartridges for EDS analysis as well as bulk specimen cartridges.
IDS:"Index Dock System"-high precision control of specimen rotation.
▶ The design of the IDS is the solution for a controlled Azimuth rotation of the specimen with CFS.
▶ The Azimuth rotation is limited to +/- 5 Degrees.
▶ With the Index Dock System, the rotation is a well-controlled process with a 1/100-Degree precision.
▶ Digitally displayed indication of the rotation angle.
Gas Flow Cover for HATA-Holder system
▶ The purpose of the Gas Flow Cover is anti-oxidation for the HATA-Holder system.
▶ If you have access to Nitrogen (N2) Gas in your TEM room, you may use flow via this unit for a few seconds.
▶ Unwanted humidity or such is avoided by the overpressure of N2 Gas and reduce contamination of the HATA-Holder.
▶ If you don't have access to Nitrogen (N2) Gas in your TEM room, you can use a small Gas bottle.
Note: If you use the Nitrogen Gas, please use Oxygen density meter for your safety.
Other considerations for ease-of-use.
▶ The index dock system is designed as a bridge.
▶ The height can easily be altered with the adjustable feet.
▶ Our idea is that you can use any of your favorite binocular stands or magnifying glass.
▶ There is a light with adjustable intensity under the specimen mounting area.
▶ It helps when you mount your sample and it let you see the actual transmitted specimen shadow.
▶ The mounting of the holder into the stand is very easy to use construction.
▶ A simple push of a button locks and unlocks the holder.
