The pump laser must be synchronized with the existing THz-TDS spectroscopy and cryogenic near-field systems. The upgrade includes a laser amplifier unit with free-space coupled optical output at 780nm, 100MHz rep rate, pulse energy >1.3nJ, >140mW output power, and customized fiber patch cord for temporal overlap of pump-probe pulses. Additionally, a transmission module enables static pump-probe measurements in transmission, where the sample is pumped via a diffraction-limited beam from the bottom and probed by amplitude- & phase-resolved near-field measurements (pseudo-heterodyne detection) from the top.", "lots": [ { "id": "1", "description": "Upgrade for cryo-neaSCOPE+xs s-SNOM system can only be provided by the base system's manufacturer - attocube systems AG.

Their exclusive design works with the following patents: * Patented parabolic mirror design for focusing and collection of light * Patented dual-port design to allow two beams of light to be focused on the atomic force microscope (AFM) tip for nanoscale imaging and spectroscopy * Patented signal processing for optical background suppression * Patented pseudo-heterodyne detection (PsHet) technology for background suppression * Patented interferometric design (nano-FTIR) for background-free optical detection technology and simultaneous detection of optical amplitude and phase and hyperspectral imaging * Patented high speed holography for multispectral imaging * Patented phase shifting detection to extract relative phase These patents and the exclusive design have enabled the neaSCOPE system to conduct amplitude and phase-resolved vector field, reflection, and absorption mapping with nanoscale spatial resolution. It is currently the only solution provider on the market that enables dual-port s-SNOM operation combined with a high NA parabolic mirror, which is essential for low SNR THz TDS and pump-probe measurements. In particular, attocube systems AG is the only company who can upgrade the existing cryogenic s-SNOM system (cryo-neaSCOPE) based at University of Manchester to perform nanoscale THz-TDS and pump-probe imaging and spectroscopy at low temperature. Therefore, the same manufacture of the pre-upgraded s-SNOM system is required to ensure: * All upgrade subsystems must be compatible with the existing microscope controls (both in hardware and software), while still being amplitude- & phase-resolved and background-free. * Pump laser must be electronically synchronized with the existing cryogenic THz-TDS spectroscopy system * Excitation wavelength must be compatible with optical windows in the cold shroud of the existing cryo-neaSCOPE system" }, "awards": [ { "id": "021633-2024-1", "relatedLots": [ "1" ], "status": "active", "hasSubcontracting": true, "suppliers": [ { "id": "GB-FTS-118469", "name": "attocube system AG" } ] } ], "parties": [ { "id": "GB-FTS-155", "name": "National Physical Laboratory", "identifier": { "legalName": "National Physical Laboratory" }, "address": { "streetAddress": "Hampton Road", "locality": "Teddington", "region": "UK", "postalCode": "TW11 0LW", "countryName": "United Kingdom" }, "contactPoint": { "email": "nina.heath@npl.co.uk" }, "roles": [ "buyer" ], "details": { "url": "http://www.npl.co.uk", "classifications": [ { "scheme": "TED_CA_TYPE", "id": "BODY_PUBLIC", "description": "Body governed by public law" }, { "scheme": "COFOG", "description": "Research" } ] } }, { "id": "GB-FTS-118469", "name": "attocube system AG", "identifier": { "legalName": "attocube system AG" }, "address": { "streetAddress": "Eglfinger Weg 2,", "locality": "Haar", "region": "DE", "postalCode": "85540", "countryName": "Germany" }, "roles": [ "supplier" ], "details": { "scale": "sme" } }, { "id": "GB-FTS-156", "name": "NPL Management Ltd", "identifier": { "legalName": "NPL Management Ltd" }, "address": { "streetAddress": "Hampton Road", "locality": "Teddington", "postalCode": "TW11 0LW", "countryName": "United Kingdom" }, "roles": [ "reviewBody", "mediationBody" ] } ], "buyer": { "id": "GB-FTS-155", "name": "National Physical Laboratory" }, "contracts": [ { "id": "021633-2024-1", "awardID": "021633-2024-1", "status": "active", "value": { "amount": 262370, "currency": "EUR" }, "dateSigned": "2024-07-15T00:00:00+01:00" } ], "language": "en" }
