Home-grown Innovation To Achieve Breakthroughs In Critical Technologies

During construction, HEPs has scored major breakthroughs in several critical technologies.

HEPs independently developed and commissioned a 166 MHz superconducting module-the world's first quarter-wave resonator (QwR) active superconductingcavity for particlesat light speed ⟨ β = 1 ⟩ ,featuringdeep higher-order-mode suppression.

Storageringwithseven-bend-achromatlattice

HEPS solved the international challenge of coating 6-mm slits in 1.2-m-long ante-chamber vacuum chambers.Three coating systems coated 918chambers totaling ~ 1 2 0 0 ~ \mathsf { m }

HEPS proposed and built the world's first"mango”wiggler; its speciallydesignedx-ymagneticperiodsdelivera large-fieldX-raybeam forimagingwithhigher spatial resolution thanconventional wigglers.

Representative Breakthroughs AndIndustrial Applications

Theplatform hasachieveda seriesof breakthroughsinkey instrumentsand researchmethods, offeringdisruptive“toolsforfrontierstudies:

Novel Wearable Meg Technology

Awearable atomic-magnetometer MEG wasdeveloped.Operatingat room temperature,it delivers mm/sub-ms spatiotemporal resolution,enables long-duration wearable recordings, and cuts operating costs by two orders of magnitude compared with conventional cryogenic MEG.Its containerized mobile design allows easy deployment in hospitals,communities and beyond,greatly extending itsreachinbrain-scienceresearch,disease diagnosisand brain-machine interfaces.

15.2tUltra-high-fieldMriScanner

Advanced integrationyielded China'shighest-field15.2TMRl scanner.Itprovides 1 0 0 0 m \tau / m maximum gradient strengthand10.000 \tau / { m } / { s } slewrate,carriesa4-channel RF receivearray andcryo-probe,and supportsmultinuclear imagingof'H,iP, ^ { 1 3 } { \mathsf C } 23Na,1F,²H.Theultrahigh field pushesin-vivoanimal imaging tounprecedentedspatial resolution,offeringapowerful tool for neuroscience,cognitive science and clinical disease-mechanism studies.It also serves asa critical test-bed forperformanceevaluationanddesign optimizationof novel brain-machine-interface probes and electrodes.The scanneris now open for external booking and isalreadyused bythe Instituteof Biophysics,Peking University,the Instituteof Chemistry, theUniversityof Chinese Academy of Sciencesand others,markedlyenhancing Huairou ScienceCity'sanimal-imagingservicecapacity.

Multimodal Behavior-coupled“Cognitive Basic Unit"ParsingParadigm

Byintegrating high-precisioneye tracking,visual presentationandlimb-motiondetection intoa “trinitytheplatform hasbuilta“super-resolutionmicroscope"forcognitivescience-the multimodal behavior-coupled“cognitive basic unit"parsing paradigm.It underpins a theoretical frameworkof“multi-cognition,multi-discipline,multi-scale,multi-evolutionary-level"andtargets thecorequestionofdefiningthe“cognitivebasicunit."

The Platform's Core Capabilities Are Now Being Translated Into Market-facing Services Across FourIndustrial Directions:

Brain-machine interfaces:services include neural-signal decoding,closed-loop modulation systemsand high-performance interface-devicetesting formedical-rehabilitation equipmentfirmsandneuro-technologycompanies;

Artificial intelligence:delivers brain-inspired algorithms,cognitive-computing models andconvergent intelligent systems for Al R&D institutesand technology enterprises;

MRItechnology:ofers shared accessto ultrahigh-field scanners,sequence optimization andmultimodal fusionsolutionsforresearch institutesand medical-devicecompanies;

Novel MEG technology:promotes wearable MEG devices for research,clinics and education,serving hospitals,universitiesand health-techcompanies.

Going Forward,The Platform Will Advance SynergisticallyAlong ThreeAxes-scientific Breakthroughs,Industrial Translation And Capability Building:

It will tacklemajorquestionssuchas the“cognitivebasic unit”using the 15.2T MRl, wearable MEGand othercuting-edge instruments,and will promote innovationand application of multimodal research paradigms.

Atechnology-verificationcenterwillbeestablishedtotranslateand incubate brain-machine interfaces,rehabilitationmedicineand brain-inspired intelligence, co-buildinglabswithindustrytoacceleratecommercialization.

Equipmentaccesswillbe broadened,synergieswithother Huairou Science City facilities willbestrengthened,and international academiceventswillbe hosted toraise the platform'sglobal reachand service level.
