Next week we’re at EUCAS in Glasgow with Lake Shore Cryotronics
The European Conference on Applied Superconductivity (EUCAS) comes to Glasgow next week, running from the 1st to the 5th of September.
Lake Shore Cryotronics are exhibiting from Monday the 2nd., and Elliot Scientific will be supporting them in demonstrating their range of sensors and instruments for cryogenic temperature measurement and control.
The conference and exhibition will be taking place at the Scottish Event Campus (SEC) on Exhibition Way.
Lake Shore’s 8600 VSM updated… Noise floor reduced to 15 nemu
Lake Shore Cryotronics continues to up the performance of their 8600 Series VSM, with the release of a new brochure covering the improved noise floor specifications.
The 8600 Series offers a clean, ergonomic design to simplify the researcher’s interaction with the system. For example, a motorised head brings the sample to a comfortable height for easy, one-handed exchange of the sample rods. And combining high sensitivity, rapid measurement speeds, and ease of operation for faster and more accurate measurements further adds to the convenience these systems offer.
Temperature options include a cryostat, high-temperature oven, and single stage variable temperature insert. The combined temperature range of the options is 4.2 to 1273 K, and all three options quickly slide into place and are auto-detected by the system’s software – video demonstration.
8600 Series Features
- Noise floor now 15 nemu
- 10 ms/pt data acquisition rate
- 5000 Oe/s field ramp rate
- Rapid, repeatable temperature option exchange
- High stability: ±0.05% per day
- Fields to 3.26 T
- Widest available temperature range: 4.2 K to 1273 K
The magnet poles are also easily adjusted with a specially designed indexed positioning system that allows the pole gap to be set at one of six repeatable positions, eliminating the need to recalibrate after each change.

Measuring Earth’s magnetic field strength and orientation
The new F71 Multi-axis teslameter from Lake Shore Cryotronics features in an excellent video on the YouTube channel of Brainiac75.
In the short film he demonstrates how to measure Earth’s magnetic field strength and orientation with the instrument’s sensitive 3-axis probe, proving how much easier it is to do so without using a compass, magnets or a protractor – you need to watch from the beginning to see this bit.
Brainiac75 features a lot of magnet/magnetism related material on his channel, so it’s well worth a look. It may get stuck on you, as we were quite drawn to it!

ICEC27-ICMC 2018 opens next week. Meet Lake Shore on the exhibition days.
The International Cryogenic Engineering (ICEC) and Materials (ICMC) Conferences are taking place in Oxford from September 3rd to the 7th.
ICEC27-ICMC 2018, to give it its correct name, also includes two days of exhibition for cryogenic related businesses. Accordingly, our good friends from Lake Shore Cryotronics will be flying in from Columbus, Ohio, to be on hand to talk about their extensive range of products for research in low temperature big and little physics, materials and superconductivity, cryobiology and more.
As Elliot Scientific supplies Lake Shore products within the UK and Ireland, our Dr Perry will also be on hand to assist with any enquiries on the Tuesday and Wednesday (5th & 6th September).
Both the conference and Lake Shore are celebrating 50th anniversaries this year. It is fifty years since ICEC was first held in this country, and also fifty years since Lake Shore manufactured its first product.
August 2018 newsletter now online…
The Elliot Scientific August newsletter is now available. In this issue an IPG laser, Lake Shore temperature sensors and Siskiyou IXF components are used in a breakthrough Los Alamos & University of New Mexico all optical cryocooler; microscopists can benefit from Elliot Scientific Optical Tweezers, the Mad City Labs RM21 platform, and microspectroscopy from CRAIC Technologies; plus ICEC27-ICMC 2018 in Oxford and more…

From near absolute to over one thousand degrees – Lake Shore have a sensor to suit
With the UK’s record breaking hot weather continuing, we thought you might like to know that Lake Shore Cryotronics offer four types of sensor for temperature measurement:
Diodes
A diode temperature sensor is the general name for a class of semiconductor temperature sensors. They are based on the temperature dependence of the forward voltage drop across a p-n junction. The voltage change with temperature depends on the material. The most common is Silicon, but Gallium Arsenide (GaAs) and Gallium Aluminium Arsenide (GaAlAs) are also used.
Resistors
These sensors are based on the change of resistance with temperature, and can be classified as positive temperature coefficient (PTC) or negative temperature coefficient (NTC). Platinum RTDs are the best example of PTC resistance sensors.
Capacitors
Capacitors are also used for low temperatures, but usually not for temperature measurement. Capacitance temperature sensors have the advantage of being insensitive to magnetic fields, but they commonly experience calibration shifts after thermal cycling.
Thermocouples
Thermocouples are only useful where differential temperature measurements or low mass are the main consideration. They must be calibrated in-situ as the entire length of the wire contributes to the output voltage if it traverses a temperature gradient.
Each type sensor has its own particular advantages in terms of temperature range and response, as well as design features and drawbacks, so Elliot Scientific recommends contacting us to discuss your application and its requirements.
Lake Shore also do some nice instruments to go with their sensors!
Laser Focus World features Siskiyou IXF mounts on cover for Los Alamos/UNM story
The July issue of Laser Focus World magazine uses a photo of a YLF:Yb crystal mounted between two top-adjustable Siskiyou IXF monolithic tip/tilt flexure mounts to illustrate their feature story on an all-solid-state optical cryocooler developed by the Los Alamos National Laboratory and the University of New Mexico.
Solid-state optical refrigeration uses anti-Stokes fluorescence to cool macroscopic objects to cryogenic temperatures without the annoying vibrations typically introduced by mechanical cryocooling systems.
The crystal was excited by a low power linearly-polarised continuous-wave fibre laser by IPG Photonics, while the temperature was monitored with a calibrated DT-670-SD silicon diode from Lake Shore Cryotronics.
Coupling the laser light to the crystal was achieved by using an astigmatic Herriott cell, with the optics held in vacuum compatible Siskiyou IXF flexure mounts… known for their excellent mechanical and thermal properties.
Researchers in the UK or Ireland wishing to replicate this experiment can contact us for research lasers from IPG Photonics, sensors and instrumentation from Lake Shore Cryotronics, and the full range of mounts and stages from Siskiyou. Elliot Scientific can also be approached to supply optics and custom machined parts as well.
The full paper describing the experiment can be read here on nature.com.
Lake Shore reaches half century… wants your stories.
Lake Shore turns 50 this year and the company intends to commemorate this achievement by putting together a special publication entitled Lake Shore Cryotronics: The First 50 Years.
So, they want to hear from customers who have, in some way or another, worked with Lake Shore. Be it as an employee, a trading partner, or as a user of their products.

Lake Shore Cryotronics introduces F-series Teslameters
The new F41 Single-axis and F71 Multi-axis Teslameters from Lake Shore Cryotronics offer a new level of precision and convenience for engineers, QC technicians, and lab researchers. In conjunction with a new series of compatible Hall probes and 2Dex™ Hall sensors, users can measure with confidence in challenging applications.
The TiltView™ display makes them easy to operate even when mounted in the bottom of a rack or on the bench, and probe swapping is now much faster due to a compact quick-release connector and integrated calibration data for all probes.
TruZero™ technology
Lake Shore’s TruZero™ technology eliminates the need to perform frequent zero gauss chambering as an onboard algorithm combines the sequential Hall voltage readings in a way that eliminates any offsets due to misalignment and thermoelectric effects. It also improves precision and accuracy.
Please contact us for more information.
