The first cryogenic permanent magnet undulator (CPMU) in China, developed by the Shanghai Light Source team, has recently achieved high flow strength testing on the Shanghai light source storage ring. When the storage ring was operated at 3.5 GeV/240 mA and the undulator was operating at a minimum magnetic gap of 6 mm, the experimenter used a 17 U beam line to perform spectral measurements and obtained clear 9th harmonic radiation with a corresponding magnetic field phase error of 3.5. °, reaching the advanced level of similar equipment in the world. This marks that the Shanghai Institute of Applied Physics of the Chinese Academy of Sciences has embarked on a new stage in the development of high-performance undulator technology.

High-performance permanent magnets have a high remanence and a high coercive force at low temperatures. Using this feature, the permanent magnets in the vacuum undulator can work in the liquid nitrogen temperature region, which can increase the peak magnetic field of the undulator. 20%. After four years of hard work, the Shanghai Light Source team solved the key technical issues of high-performance neodymium-iron-boron permanent magnet preparation, permanent magnet cooling and temperature uniformity control, and measurement and shimming of the undulating magnetic field in cryogenic and vacuum environments. Based on the vacuum undulator technology, a low-temperature permanent magnet undulator based on neodymium-iron-boron permanent magnet with a cycle length of 20 mm, a cycle number of 80, and a minimum magnetic gap of 6 mm was successfully developed. The undulator was installed in the linear section of Shanghai Light Source Storage Ring C17 in August 2016. After temperature compensation, beam cleaning, and small beam flow tests, it cooperated closely with the 17U beam line and successfully completed the high-strength beam current test. At the 12.66 keV common photon energy, a photon flux of 40% higher than the current 17U ambient temperature vacuum undulator with a cycle length of 25 mm and a cycle number of 80 was measured. The crystal structure analysis experiment of the protein was performed using the undulator irradiation. At present, the Shanghai Light Source team is also conducting the development of low-temperature permanent magnet undulators and superconducting undulators based on neodymium-iron-boron magnets, with a view to further improving the performance indicators of undulators and serving the needs of beamline engineering and user experiments.

General Safety Information:

1. Check if the plug cord was in good condition, and if there is stand before plug into the electrical outlet ; Check if the used glue gun has glue flow through back of the tunnel;

2. wait 5-10 minutes to allow glue to soften, stand up the glue gun on the table when not in use;

3. Touch nozzle to any clean, dry surface you wish to bond, to avoid any impurity stop the nozzle;

4. If the glue could not flow from the nozzle when the glue gun start to work, check if the glue gun are heating;

If glue gun can not be heated, there are following reasons:
1 Plug cord into electrical outlet not properly;
2 Glue gun has been destroyed owing to inner cord short circuit;

If glue gun can be heated, there are following reasons: Nozzle has been stopped by any impurity, ask careerman to manage it.

5. Do not use the glue gun under moist climate, humidity will affect insulation and cause electric shock;

6. Do not touch the nozzle or melted glue;

7. Do not remove out the melted glue stick from the tunnel back side, it will damaged the glue gun as well as scalding person hands.

8. Do not to disassemble or assemble any glue gun accessories freely, it will cause glue gun do not work properly;

9. Keep out of reach of children and stocked it beyond any of Children palpable side;

10. Only used for melting glue stick, no other usage;

11. When in use, there are any glue flow back from tunnel, stop using immediately, wait for careerman clean the glue;

12. Close the power if the glue gun not in use after 15 minutes;

Important Caution:

1． Before use the glue gun, check if the plug cord into electrical outlet properly;

2． When glue gun in first use, the heating element will have small smoke, it is normal situation, but the smoke will disappeared after 10 minutes;

3． After power, not for a long time in standby mode(not longer for 20 minutes), when the suspension of use, unplug first.

4． Avoid to use the glue gun under very hot or very cold environments.

5． Better not work under direct cold wind blowing, it will reduce efficiency and loss power

6． When in continuous using, do not press the trigger with great pressure, and try to squeeze out the un-melted glue, it would damage the glue gun

7． Not applicable for bonding heavy objects or objects needed strong adhesive

8． The quality of glue stick will directly influence the glue gun function and sticking objects quality;

9． If the power cord is damaged, do not replace it by yourself, must ask for professionals to replace it.

10． This tools must b e placed in its position when not in use. And storage before the tools complete cooled.

11． Be careful when using any other electrical appliance with flammable material.

12． Not applicable for a long time in the same place.

13． Do not use an explosive gas atmospheres.

14． Note that heat may be the line of sigh, combustible materials.

15． Do not leave equipment unattended when switched on.

16． This appliance is not intended for use by persons(including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

17. Children should be supervised to ensure that they do not play with the appliance.

Using methods

1. Glue gun using voltage is 110-220V AC,50/60Hz;

2. Tip gun forward on stand and place a piece of cardboard under the nozzle

3. Use 7-8mm (mini trigger glue gun), 11-12(big trigger glue gun), insert glue sticks through
tunnel at back of gun

4. After power, wait for 5-10 minutes to allow glue to soften
